I don't want to threadjack, but being pro-abortion means not messing with semantics when it comes to just what abortion is. Abortion is the deliberate termination of a pregancy on purpose. And I'm all for the right to do so.
Any woman should be able to have an abortion, for any reason she wants to, as long as she can pay for it herself, and no man has the right to even hold an opinion on the subject.
If men got pregnant there would be McBortions on every street corner.
That said, a man should also have the right to not be a father if he doesn't want to be one. If a woman decides to have a baby, and the man doesn't want it, then he should be absolved of all responsibilty for it. That means no child support, and his name stays off the birth certificate so the little darling can't find him later and bother him.
Why anyone has kids on purpose is beyond me.
