I am new to this forum and I just need a male's opinion on this friend I have..

We met through a mutual friend and we've been cool for about 5 or 6 years. One of the things that I dislike the most about him is that his character can get VERY ugly. If any of his black female friends associate with a non-black guy on a platonic level he gets very aggitated and starts saying negative and nasty things like "I bet you're going to be his wh0re." or "those white guys just use black women for sex." He doesn't like it when his black female friends mention White men in the media who are attractive. None of us are even remotely interested in dating White men, but occassionally will just say somethng like "Brad pitt is good looking" It's not like they are chasing after non-black men, or putting him down because he is not White. Yet, he himself have talked about several non-black women who he has found attractive i.e Kim Kardasian Lastly, he threatens to end our friendship if I ever dated a non-black guy

Our friendship has been off and on, we have gotten into discussions where he has hurled all kinds of demeaning remarks like calling me a "wh0re" and saying "I just want to suck a White man's d1ck" and saying that "i'm jealous that I don't have beautiful hair like a white woman" all because my political views might be similar to a man who happens to be White. Once he got so out of control that I hung up the phone on him, and threatened to end our friendship because of his unnecesary behavior. He is an adult, in his 30s and far too old to act like this.

I really just want to understand why he cares so much about what race of men I date. If I mention a guy that I met, he'll ask if he is black. I just find that so odd because for as long as he has known me I have never been the type to express any genuine interest in non-Black men. I really put off hanging out with him in person alot because he makes me feel uncomfortable and I just don't trust him.

Guys can you help me understand this...is there something more behind his erratic behavior??
