First one that comes to mind, there's two guys, ones proposing to the other. Two male parents kiss Here, you have presumably a brother and a sister going after the same guy There's another one I've seen but can't remember what company it was but... Very subtle, but there are lead character is holding hands with another woman at the start
Wait this is like supposed to be positive? Haha oh I'm in the wrong thread then. Most advertisements that have gay guys in them feel inappropriately 'token' to me. It's almost like in an effort to accomodate or appeal to the interests of gay people, advertisers are somehow making it even worse. Most of the ads featuring (obviously atypically attractive, same goes for women in 'straight' commercials) gay men I see seem fake or just make me feel inferior, offended, or depressed.
A while back there was an ad for Illinois tourism, focused at LGBT people. The ad showed same-sex couples enjoying the state together, and ended with a rainbow-colored graphic of the state.
