I happen to be a straight christian guy, and honestly yes it does bother me if I see two guys, or even two girls making out. Course seeing a guy and a girl makeout doesnt necesarily make my day, but its really not that big of a deal.
If I had the power to, and im sure this will confuse alot of non christian people, but I wouldnt outlaw homosexuality, (although I would probably make it so that they could have unions with all the same benefits of marriage except for the actual word.) And before you say, "Thats unchristian like" or even, "Thats not a big deal several churches think homosexuality is ok" first off, the reason I would do this is simple, when the creator made us, he gave us that beautiful gift of life, that gift of choice, sure he wants us to follow the laws he laid down, and he hopes we do, but he gave us that choice to do things that he disagrees with. If we had been made to be his slaves and always agree with him, that wouldnt really be much of a life now would it? Just because I disagree with you doesnt mean I hate you, tolerance is the foundation of the nation I live in. And second, no, you CANT be a christian and a homosexual, either you follow all of the bible, or you follow none of it, its that simple, so no real church allows it.
So to answer your question, yes it would bother me, but thats just me, and even if I were in a position of power I would not attempt to stop public displays of affection, mostly cause its pissin me off what they are complaining about now a days, what with video games, and then that awesome billboard that said, "We're like a cult... just with better Kool Aid." Makes me sick. Course I'm a pretty darn tolerant person so I assume few will agree with me.
