People are still people no matter what.
If they're gay
If they're lesbian
If they're bisexual
If they're straight
It shouldn't, no, it DOESN'T matter. We are all humans and we should all be given the right to love whom we please, no matter the gender. A man and a woman can marry, but society sees it as 'wrong' if a man marries a man, or a woman marries a woman. Why is this? Everybody should have the same right to love. To marry who they want to spend their lives with, regardless of the couples' sexuality.
