Um, you're a white girl in the South. 'Nuff said. If someone is saying things of this nature to you/around you, speak up and say nicely, "I don't feel that way and I think racism/sexism/homophobia/whatever is wrong--and no, I don't feel like explaining myself. Let's talk about something else or nothing at all." People may assume that it's okay to air these opinions around you because you haven't said otherwise.

Also, to quote a political commentator (who, yes, is a Republican, but whatever), picking Joe Biden for VP is like walking into Baskin Robbins and picking vanilla. WHO THE FUCK DOES THAT?
