There are so many facets to this subject that it is hard to take them all on.
I support the legality of abortion because I think it should be available for cases such as rape and other extreme cases where the mother's life may be at risk and other such things. I do not agree with the use of abortion as means of birth control, but in order to keep things legal for good reasons, you must accept the bad along with them. Besides, when it comes down to it, no matter how I feel about abortion, it is not my place, no matter how abhorrent I find the practice, to make decisions for anyone else. This is simply my opinion on the matter.
On a separate note:
This is not good enough. So much more needs done. It is not enough just to see a baby live. It is to see that they are cared for. Can be cared for. There are many in this world that are sick and starving to death. Malnourished. Abused. Instead of just pushing against abortion like nuts, why not rally for programs that would ensure that the babies that are born have good homes to go to? Have nutritional food and clean water? Have good parents? Just pushing against abortion isn't going to help matters until programs are in place which not only work towards taking care of the babies born, but also work towards reducing the perceived need for abortions in the first place. Namely, education and availability of birth control methods.
Look, I don't particularly like abortion either, but I see that it can serve a purpose in some cases at the very least. But rallying against it by calling all who get one a murderer isn't going to actually accomplish anything. It really isn't. You want to reduce the number of abortions? You want to make a difference? Get out and educate people about different forms of birth control. Hand out condoms. Get involved in some way other than throwing around the word "murderer".
