Those who react negatively to this imagery in defense of the KKK/Nazis are the ones you need to be worried about.

That is a wild statement and my entire point. That's your thoughts, some people dislike violence full stop, regardless of who is committing and who is suffering the violence. I'm honestly struggling to think of a single socially acceptable place to wear the t-shirt outside of a protest. Even then, it's like you're hoping the protest turns into a riot.

Edit: and further, who the fuck said the KKK isn't inflammatory etc? You guys really need to sit the fuck down and have a think about the shit you are spewing.
