Personally I'm pro choice because I think it would be better that a child not be born, then to be born to someone who didn't want them. It sounds cruel, but its the cold, hard truth. Its sad, and I understand that, but if someone doesn't have the money, maturity, or ability to care for a child...
The reason that democrats tend to be labeled as socialists is because many (not all!) seem to enjoy getting money from the government... a little too much. Personally, I would rather work for my wealth than have it given to me... but I'm a republican.
