As a staunch pro-lifer (adopted when I was 4 days old, in 1976, bio-father was married and pressuring bio-mother to have an abortion) I can't argue with people who are pro-abortion because it makes me irate.
It comes down to this: Is murder wrong? yes or no?
This whole "right to choose" is crap. You chose to have sex or not. you chose to get on the pill or not, you chose to use a condom or not. And there's even the whole morning after pill which I object to.
And don't even get me started on "rape exceptions". Rape is bad, BUT if you rape someone and you have a 6 month old son when you do, and you get caught, the penalty is not the dismemberment of your 6-month-old. And NO you aren't "forced to raise your rapist's child" unless you decide to not give it up for adoption.
Point blank, it's murder. If you accept abortion as being ok, then you are saying that you are ok with murder if the person being killed is considered inconvenient to someone else, and that is hideous.
