Why same-sex marriage opponents are sexists

There are some people who say man-woman marriage should be the only acceptable type of marriage. They say that man-man or women-women marriage should not be accepted.

If they believed that men and women are equal in a man-women marriage, then they would believe that a man-man marriage or a women-women marriage would have the same acceptability.

So those who oppose same-sex marriages believe that men and women are not equal. They are sexists.
