I have absolutely zero problem with people being gay, and I don't understand people who say otherwise, for a few reasons.
Let's say, for example, loveuality is like ice cream. I like vanilla ice cream, but, well, you like chocolate. You don't eat ice cream in front of me, sure every once in a while I might see you with other people who feel the same way, but it has no profound effect on me. I enjoy my vanilla ice cream, you enjoy your chocolate, the world goes on.
But some people are elitists about ice cream. They say, nay, nobody may like chocolate, everyone must like vanilla, and dammit, we'll make you all eat vanilla. Well, that's a problem, because you like chocolate. Sure, you could eat vanilla ice cream, but you would never like it nearly as much as the chocolate, and plus, it's kinda silly to outlaw a flavor of goddamn ice cream.
Then there are people who like both, they don't care which they have really, they enjoy both equally and are fine either way.
It all really boils down to preference, and people likely aren't going to be loving like animals in front of you, if they do, that's a crime, no matter if they're straight or gay. People shouldn't really care, because it doesn't matter in the end. People have a right to be happy.
