No, quite honestly I think they are stupid (and was called a homophobe for that once).
Having minority characters in itself is perfectly okay, overcompensating in the other direction and flooding people's media with people that barely make up 10% of the population in a misguided attempt to "promote tolerance" is bizarre.
Coupled with the fact that supporters of this idea all seem to share a very moralistic attitude and jump at the opportunity to call any critic the most extreme names they can come up with, that makes the idea pretty weak in my eyes.
