I honestly feel sorry for you. If you honestly think that ending a persons life before it begins, I feel sorry for you.
They're are no hard facts for this. There is only morals. Nobody can tell the future. You can't actually see what somebody is going to do during their life. There is no reality to uncertainty. The to-be child you are thinking about ending could be the greatest thing in your life. Ultimately, you might die during child birth. Why think of the negative? Thinking negatively never got anyone anywhere.
The only facts are. This fetus may or may not become a child. Beyond that, there is nothing.
it's not a person, infact up to 20 weeks it can't even think (even past that, it's only REM sleep that they count as "thought"), it's about as morally bad as running over a frog.
and yeah, nobody can tell the future, which is why you need to step away from your "they could cure cancer" argument. as i said before, if you want to use that sort of pseudo logic, you might want to launch a vendetta against people who have protected love and don't get pregnant in the first place; because they're equally preventing the development of life with "potential".
and don't feel sorry for me, i get to enjoy great love with my girlfriend without having to worry that we
have to have a baby should her pill fail :)
