It is not necessarily exclusionary. Blacks have been having their own private proms for many years. There can be several reasons for this. One, when it comes to dances, blacks and white often do not enjoy the same style of music. Second, and I realize this is a biggie for some people; at dances there is more intimate contact between members of the opposite sex and MANY people, black and white, do not want have those kinds of relationships with members of another race. It might be a family thing or it might be a personal thing, but either way, it doesn't make you a racist. Speaking personally, there is a couple that I work with who are also relatively close neighbors. They are black. I like them both and have no problems whatsoever with socializing with them. They bug me about going out with them to a club dancing. I also have no problem telling them that there are no white men at the clubs they go to and that is why I wouldn't want to go. They joke about it, but they are not in the least offended by it. Some people are just professional offendees and I'm getting pretty sick of hearing from them.
