I try to keep the two seperate, but sometimes those outside hobbies/interests come in to play IN their work itself, so you can't help but wonder if the two are related. I probably wouldn't have defriended her, but just kept her around to watch her (CAUSE I'M A TERRIBLE PERSON).

But still, I can see why you did, though. You have the right to not be associated with people like that if their hobbies bothers you that much. If I found out one of my friends was in a KKK group, I'd prooooooobably defriend them XD
