I am definitively pro abortion, and I do not view abortion as immoral. There are mainly two things that together cause me to have this opinion.

First and foremost I consider a human-being's right to make choices about their own life one of the most important, basic human rights that exist. In this context, that means that a woman has an immutable right to make choices about her own body, which would include aborting an unwanted fetus. And before someone makes the argument, this does not apply to the fetus. It does not have the ability to make a choice.

Secondly a fetus is not a person. As has been stated it does not properly experience the world. It does not have memories. Thus killing a fetus isn't murder. The potential to be a person simply doesn't count.
(An interesting quirk: If a pregnant woman were to damage the fetus due to neglect (for instance by knowingly ingesting alcohol while pregnant), that would be an almost unforgivable offense if intending to let the fetus live, because it would cause suffering when the fetus became a person.)

Thus the consideration for the woman simply outweighs the slight immorality of killing a living thing by so much that it's not immoral.

Also, @OP: Cool down a bit. You're currently seem to be insulting almost everyone who disagrees with you. It does not make for a good discussion.
