Some cultures are incompatible with American culture, but most of the time conservatives just use that as an excuse to complain about non-white people moving to this country. And that is racist.
Calling you a racist has always been a tool the left uses to shut down debate. They can't tell us why importing millions of people from cultures incompatible with our own is a good thing for America. They just call you racist and hope you'll shut up. Well, I never will.
