They just want to pursue for their own happiness, a person loves someone from the opposite love, same love or hell anything else really, and that's what it brings that person's true love and reason to be happy, isn't it what we're all fighting for? To be happy? Like everyone else with their own different types of loveuality? I hang out with gay/lesbian people everyday on school and they're great friends of mine, basicly they just want to be happy with the way they want to be, forcing them to like something they don't is the complete opposite and it only makes their lives worse.
