yep. lot for you to learn, grasshopper.... 
when producing ads for general audience, what do majority of ads have? mostly Caucasian heterosexual people.
so having "different people" as main spotlight rather than background is a big deal for us. deaf people on front page? GLBT on front page? mixed races on front page? wonderful! more awareness and spotlight for us! no more being a background!
I know this quite well because well I'm in marketing business and have been for quite a while..... and I also know your angle and it's really an amateurish attempt to steer it into that angle. it's a classic cheap smear politic textbook tactic. so amateurish.
