In case you're not entirely joking, I just want to reassure you it's possible, and beneficial. I was raised with three forms of bigotry, and in time I purged it all from my self. Prejudice is by its nature irrational, so all it really takes is a willingness to accept that. I don't want it to sound like I'm gloating, either. I ended up in the position of being fairly disappointed with myself for taking as long as I did.
