What is a traditional marriage?

The reasons Mormons and homophobes oppose gay marriage is because they think that a marriage is only between a male and female (and cite the Bible for their hatred). While there is no evidence whatsoever that gay marriage changes anything in society (countries and states in the USA that do have gay marriages are pretty much unchanged socially since gay marriage became legal), these die hard hatemongers still keep arguing the same old argument that no one seems to find credible.

Oh, in case, you did not know what a traditional marriage was, here is a very nice explanation.
