I should be in favor of someone else killing a human so I won't have to support them?<quoted text>
This question wasn't directed at you. And furthermore, there are things one can do that doesn't involve opening their own wallets.
So if you think people are irresponsible and you don't want to financially support them, you should be in favor of them having abortions. You're never going to stop unplanned pregnancies, so according to your logic, abortion makes sure you don't have to support "irresponsible" parents who have children.
I love liberal logic.
