What exactly makes you think that? What led you to that?
I came to the alt right specifically to help black and hispanic people. I've worked with non white people all my life and me trying to make them adhere to white standards is not fair to them.

I think our philosophy of peaceful separation is the best strategy for the long term happiness and survival of all races.

Black people shouldn't be held to white standards. They need to live in Africa with their own people and their own unique ways of governing themselves.
Latin people have their areas and need to stay there.

And to answer your question of course I'd shoot an alt right dude raping someone. If it was just a fight and I didn't know the context of course I wouldn't shoot anyone. I'd probably just try to break it up.
