I’m white, and I have never felt attacked or shamed for my race by society or liberal politics. If you see people criticizing white supremacists, neo-Nazis, and Confederate apologists and feel personally attacked, that says more about you and the company you tend to keep.
(There’s also the fact that being LGBT doesn’t automatically protect you from being a hateful dipshit, just see Milo Yanwhatshisname for proof of that).
