Who decides what is and isn’t polarising?
You?
There's polarising and there's the absolutely vain attempt to suggest there's any similarity between what she stood for and what Kirk did.
He was ok with people dying to support second amendment rights. School children. He was ok with violence against others in a political cause.
I'm not ok with any of those things.
Kirk didn't have a problem with violence against people he didn't agree with, wasn't too troubled about children dying to retain second amendment rights.
I get you're upset about his passing, but he literally died for something he believed in and was content to see others die for. I can't pretend that his death makes me particularly sad, violence is never the solution, but he wasn't too worried about other people dying for his chosen causes.
Jo Cox, as far as I'm aware, didn't want anyone to die for her beliefs, and in fact advocated for exactly the opposite during her lifetime.
