So, from the outside looking in knowing this is a tough subject to "sum up" in a few paragraphs ...
What's the end goal? I find it incredibly more insulting, demeaning, and counter productive to include someone JUST because they are white, black, female, asian, etc. It's just as discriminatory as excluding them.
In fact, in my opinion, it's far worse. It's discrimination masquerading as equality.
You want everyone treated equal? Awesome. The best speakers get in, period. You vary from that in either direction, and you are embracing inequality.
