I don't honestly care much about Kirk. He was a vile person. But I am more worried about the backlash or possibly Trump using this as a Reichstag fire moment.

Agree. There's a way to disagree with him without resorting to violence.

So a man claiming we need these shootings to maintain a right to defend ourselves against tyranny has died from someone exercising the right he protected while engaging in tyranny against a minority? Do I have that correct?

He was a professional liar, his job was to knowingly lie in order to promote Fascism. He knew what he was doing was harming millions of people, and I do mean millions, because right-wing media is seen all over the world.

I can have sympathy for average people who get duped into MAGA because all they see is right-wing media. It's a form of grooming. I can even have sympathy for Fascists who honestly believe that Fascism would make the world a better place. Same goes for Tankies.
But Kirk knew what he was doing. He deserves no sympathy, only people dancing on his grave.

I don't know him but i heard he was right wing and supported Israel

It is sadly sometimes unavoidable.

The guns are an important part of keeping US society conservative. So are the car crashes and poverty deaths.

Live by the sword, die by the sword.
