you could make the argument that every day is "white day"
you could also make the argument that every major network is "WET"..and that minorities were forced to create their own.
you point out that minorities group have created their own entities, maybe they did so they out of a lack of opportunity, maybe they wanted their kids to see someone like them on TV..how many minorities were there on "Friends" or Seinfeld..

In general I try to celebrate the differences in my friends and perhaps learn something.
in NY every "ethnic group" has a parade for some reason or the other, why not enjoy it?
hopefully we can have some discourse on this topic without getting off on a racial name calling rant..but I doubt it
