Why is it such an alien topic?

So, in life, we have straight couples. Of course, both of the opposite sex-man and woman. However, we also have gay couples. A man and a man or a woman and a woman. So, why exactly is it illegal by God to be in a relationship with the same sex. See, in my point of view, I agree that it's illegal by God because He created man and woman. But think about it, why do the so called Catholics and Christians hate it? I mean, they're just people and they're not special and even better, some-maybe most, in their religion, are gay too. So, let's get away from relationships for a second here. If it's wrong to be in a relationship with the same sex, why is it bad to experience the urge you've always felt about the same sex? I mean, it's just a one time thing, am I right? Probably not but I think I have a point. Okay, so maybe your parents may reject to it or it wouldn't be approved by your grandparents but, in discreet terms, maybe you could try it without them knowing. Homosexuality, I have to say, is such an alien topic, you know? People, just because someone is gay, it doesn't mean that they're an alien! Someone who sees a girl dressed as a boy with tattoos and holding hands with a another girl, they automatically want to talk about them or say that they'll be condemned to hell. If you hate them so much, just...I don't know, don't think about them. You know the point is that the people who hate them aren't following the road of God. If you believe in God so much, just ignore the gay people! Now look, I support gay people only because I have friends who go through the harshest comments ever. We are all equal! No matter who we are or what we like. We follow who we want to follow. I'm not saying to follow the devil but it's-and I think this goes to people who don't understand, it's not our fault we feel the way we feel. We probably didn't expect to like the same sex. That's not what I expected in my life. Let our own judgement come if we don't learn our lesson soon.
