Is being lesbian/gay bad?

First of all, what could possibly be bad about loving another person? People have been gay since the beginning of time and will continue to be gay until the end of mankind. There's nothing you can do to stop gay people from being born, so why in the world do people worry or try to find something wrong about it? What harm does it do between 2 consenting adults? No one forces it on you, and if they do, it's not because they are gay it's because they are mentally ill or an abuser. These come in both gay and straight forms, it's not a one sided thing. Another thing to think about.. if everybody in the world was straight, the world would soon be overpopulated, being gay is probably nothing more than nature's form of birth control. Very simple explanation.
