Instead of jumping into an already running conversation I'll just simply leave my opinion on the subject and my reasoning.
1.) Yes it should be legal. This is because as with all things this can come about from unwanted circumstances, (Condom breaking, rape, etc) so there should be an opt out as well.
Even so there should also be taken into account the randomness of life to the point where you could be stable for a child at one point and a week later barely able to provide for yourself. While its true many people would just still have the baby, (lacking the common sense to realize how their actually continuing the agony longer than need be) people that actually logically think things through are ostracized for simply understanding they can't take care of the baby.
2.) I fully believe that any consideration for the "feelings" or the "future" of the fetus are moot points and completely irrelevant to this topic.
As for "feelings", sorry but all the fetus is, is a collection of cells. It has no more capacity to feel than a tumor forming on the inside of your colon. Actually if you think about the processes each preforms, the tumor probably has a more responsive system than the fetus but I digress. The fact of the matter is, it isn't alive on the level people would like to think it is.
As for it's "future" as a human being, well I'll dive more into this point on my next subject but simply put, we live in a reality based solely on the idea of probability, if you simply make a decision based on the idea of "could be" then you have absolutely no thinking process at all because this is basic to every action and consequence in every part of our lives.
3.) (Please don't reply to this portion without strong reasoning as to why I am wrong. I will not respond to basic idealogical arguments based on the sanctity of life)
I personally believe abortion should not just be legal, but required in some circumstances. Such circumstances which would be included are:
-Families who keep having kids yet cannot support them, these are becoming more and more prevalent in todays society. Women are seeing having children becoming less of a responsibility and more of a measure of stature, meaning they simply have children because they want children. Resulting in very little regard the childs future. Now this could go against what I said earlier and mean I'm looking at the fetus's 'future' however because of the womans situation I can make more of an educated guess than rely solely on probability.
-A child would be born which a severe illness (Let's say..leukemia?), and they would only live for 5 years (best medical guess). However the parents still have the baby because they want someone to love and want to give the child all the love they can give.
Because they have made this selfish decision, this child had to live through 5 years of unending pain just to inevitably die. We are seeing this more as well, people are taking professional medical opinions and throwing them at the wind because they think they know better, yes your kid has a very slim chance of surviving but is that really worth putting them through all that?
-Someone has a child who is deaf and blind and can't move their arms or legs, yet they still have them because they want a kid. They are warned of these problems yet they don't retract the pregnancy. Now we have a member of society who will never be able to contribute anything and will always need to be cared for.
