The problem are your silly, sanctimonious rants.
You talk about how people can't go into certain areas and use certain slurs or they won't come out alive. I've been called all kinds of slurs like cr@cker, h@nkey, etc. I never thought it gave me the right to kill or assault anyone. And to be fair, no one called me that unless they had a group of friends around to ensure they had a 5-to-1 fight if I got mad and took a swing.
If a non-white goes into a nice, 98% white community and starts yelling racial slurs, is it okay for the folks there to give them a beatdown? Because I'm 99% sure you'd be crying online about it and talking about how it set race relations back 100 years, etc. The reality is that almost never happens but this does.
