I am not grieving only a man. I am grieving a boundary. There are lines in a civilization that do not get crossed if we intend to remain a civilization. Elections can sting, policies can harm, rhetoric can humiliate. Yet the line that says we will fight with words rather than weapons is more than etiquette. It is a covenant. When someone kills a public speaker for his words, the harm is not restricted to a family or a movement. The harm punctures a membrane we all depend on to breathe.

That membrane is thin. We pretend it is steel. It is actually something more fragile and more sacred. It is a shared promise that persuasion will substitute for violence. I have devoted myself to that promise. Not because I agree with every voice that carries a microphone, and not because debate is tidy, but because the American project requires a public square where arguments collide without bodies falling. My fear for America has never been centered on any single law or politician. It has been a fear that we lose the muscle memory for disagreement without dehumanization, and once that memory fades, force looks efficient.

Why does this hit me personally, beyond the headline? Because what died on that stage is the plausibility of my operating thesis. I have said, often and loudly, that curiosity can save us. Talk, listen, ask, ponder, consider. Let ugly ideas surface into the daylight so they can be tested, not buried where they metastasize. An assassination is the anti-curiosity. It declares that the other person’s mind is not a terrain to be explored, it is an obstacle to be removed. That is not a policy shift. That is a cosmology shift.

There is a deeper wound here. We have sacralized politics. When a society loses confidence in the transcendent, it tends to convert politics into a substitute religion. Heretics then become blasphemers, and blasphemy invites punishment. Assassination is political blasphemy control. It is not the assertion of a superior argument. It is the assertion that arguments no longer matter. I can disagree fiercely with a man’s conclusions and still insist that he remain a living opponent. When he is shot for speaking, I am forced into a new metaphysics of fear, one where my children inherit a public square that must be entered like a war zone rather than a classroom.

René Girard wrote about mimetic violence, how communities channel tension into scapegoats. We are playing a dangerous version of that game. The point is not whether Kirk was right or wrong on immigration, universities, or elections. The point is that a crowd trained to seek purification through sacrifice will always find the next body. Violence argues nothing and teaches nothing. It only recruits. That is why the grief is mixed with dread. Violence simplifies by slaughter. It offers the seduction of resolution without the work of understanding. It feels decisive and is actually stupid.

There is also a moral injury I cannot ignore. I took an oath as a naval officer to defend the Constitution. The First Amendment is not a decorative preface. It is the engineering that keeps pressure equalized across a pluralistic hull. I have lived inside steel tubes under the ocean where pressure is not theoretical. You respect pressure or you die. Speech is how this Republic equalizes pressure between worlds that do not share instincts, histories, or gods. When someone punctures that system, I feel it in my bones as a violation of craft. They are tampering with the ballast. They are courting implosion.

Another layer of grief is the way assassination colonizes the imagination. After a killing, everyone is tempted to become a novelist of motive. Each side writes a convenient plot that confirms its priors. This is the great theft after the murder. The dead person’s humanity becomes raw material for other people’s certainties. I have been working to pry citizens out of their echo chambers and into a posture of patient inquiry. Then a bullet arrives and rushes us back into the easiest narrative grooves. Click. Share. Condemn. Revenge. Curiosity is the first casualty in that stampede.

The philosopher Isaiah Berlin spoke of value pluralism, the sobering idea that worthy human goods often conflict and cannot be fully harmonized. A mature society learns the art of tragic balance rather than holy war. Assassination is the rejection of tragic balance. It implies that one value set is so pure that the continued biological presence of its critic cannot be tolerated. That is adolescence wearing moral armor. It cannot sustain a Republic.

So I feel grief, but I also feel a sharpened responsibility. Not a performative call to unity. Not a sentimental call to “come together.” Something grittier. I will not let murder dictate my posture. I will not allow a gunman to set the terms of my attention. Attention is a resource. In an economy of outrage, attention is currency. I will spend mine on the hard work that violence tries to shortcut. That means seeking out the thoughtful opponent, not the caricature. That means refusing to speak about political strangers as if they are metaphysical threats. That means treating speech as a sacred engineering control, not as a theatrical weapon.

I am also making peace with a humbling truth. Most arguments do not end with conversions. I have said this for years. We rarely win in the moment. We seed, we water, we wait. Assassination is a tantrum against time. It says, I will not wait for the slow victory of persuasion. I would rather counterfeit victory with a fatal interruption. The counterfeit will not hold. It never does. It breeds imitations and it starves understanding.

Why does this affect me so much? Because it tries to make a liar out of the best parts of me. The part that believes Americans can still do hard things together. The part that believes my oath is not a relic. The part that believes kitchen tables can outperform capitols. If I surrender those beliefs, then the shooter gets more than a life. He gets my future posture. I will not allow that.

What, then, is left to do? The same work I set out to do before the shot was fired, only with deeper resolve. Build narrow bridges in nearby places. Refuse the intoxication of totalizing stories. Ask real questions. Listen for the real reasons under the rehearsed ones. Treat your interlocutor as a mystery, not an algorithm. Accept that disagreement is not a design flaw. It is the playground where free people practice not killing each other.

Curiosity is still my wager. Not a soft sentiment, a discipline. Curiosity forces me to examine my own blind spots and dignify the other person’s interior world, even when it repels me. If assassination is the gesture that says words are futile, then disciplined curiosity is the stubborn reply that says words remain our lifeline.

I am grieving a boundary. I am defending it with the only tools that can make it real again. Speech that honors persons. Attention that resists rage. Courage that refuses to outsource the future to the loudest or the worst. I cannot guarantee this will be enough. I can guarantee that abandoning it guarantees our decline. America has survived other ruptures because enough people recommitted to first principles when the principles looked weak. That is the assignment in front of me, and I accept it.
