There is absolutely nothing wrong with gay marriage. Kids are going to be picked on all the time no matter what. It's just part of life, you can't get around that. Even if a kid has two dads or not, someone will find something to pick on him for. That's high school for ya.
Also, who is it hurting for two of the same kind of people to get married? No one. You aren't being forced to look at them, it's not affecting you in the slightest way possible. if two people want to be happy, then they should be. Is there a law saying people can't love? That's what they're doing. they're loving. there's nothing wrong with two people having a loving marriage. its not like I'm walking up to you and punching you in the face every time a gay couple walks by. You want to make laws so people can't be happy? That's bull**** in every way.
Gay people are some of the nicest people you will ever meet. That's stupid if you want to have people not be happy.
