Politics question

Isn't it weird to prefer adoption to abortion, but to be against gay marriage? I don't get that, but they're associated.

Maybe the idea of pro-life is that people should only get pregnant responsibly. Er. Despite its name, then...

or that everyone can deal with having a kid (or give it to some other family member) so the choice should never be made at all? although that sounds more like an assumption than a position.
