Maybe.
But I tend to think of these things from the marketing perspective: a viewpoint becoming part of the culture.
Apart from it being cute, these things chip away at the bigotry.
It really helps that:
1.They're female
2. They're hot
At this stage, that's better marketing than two hairy blokes playing tonsil tennis.
Check out the reactions below the article, still plenty of bigotry to go round.
But the culture is changing. And in a democracy, political leaders only start to promote things that are already part of the culture. It's the only way to win elections.
Eventually politics will side with gay rights, and I like that just fine.
Sorry for rambling post. I'm at work and in a hurry.
Hope I make sense.
