After gay marriage is allowed, and gays are not denied their rights, whose rights to we take next?

We need to see it that men quit being denied their right to marry little boys. After all, it's like we are telling these men who they love and who they don't love. And those poor little boys can't marry the man that they love. I can't believe that such basic civil rights are still being violated in this country. And why can't a human marry an animal? How is it that we supposedly give animals the rights they deserve, but we don't give them the right to marry humans? If a human is truly in love with an animal, then that human should have the right to marry that animal and get the same treatment from the government as everyone else.
