3% of the population is gay (if that). I think many, many straight people have a biological aversion to watching people of the same sex make out. Even people in favor of same sex relationships get grossed out. Doesn’t make them a bigot.
I guess you’d like to force the bigot to bake the cake, though.
I don't want to see a gay couple make out any more than I want to see a straight couple make out.
What if it's an elderly hetero couple making out? Or a morbidly obese man and woman making out? I mean, those are pretty icky too, and I definitely don't want to see that. Shall we have a requirement that only good looking, hetero couples under 35 are allowed to make out on TV or in public?
