While no one here has made this point, one of the things that amuses me about the arguments against gay parents is the argument that gay parents will raise a gay child.

Erm, where do they think gay parents come from?

For the most part, gay parents were born of and raised by heterosexual parents.

If that argument that gay parents will raise gay children is valid, then all people raised by heterosexuals would be heterosexual, and that's clearly not the case.
