I'm not really feeling intellectually energetic enough to argue properly right now, but here is a summary of my views:
Liberals espouse intellectually dishonest arguments for measured benevolent reasons, they want to make it an easier decision for troubled women to make.
It's very telling that said liberals have recently resorted to saying that even babies outside of the womb are not full persons and a less important life than older humans. I think the reason for this is actually a kind of pre-emptive. It's pretty clear that late term abortions and viable premature births coincide. The point is, without this new change in liberal thinking, they would have been left with a totally arbitrary point of birth definition of a babies personhood.
The whole debate is full of very scientific thinking people who are somewhat annoyed and offended by the idea of their being such a thing as a potential person and of that potential person having some kind of rights, but I would say that despite the obvious hole in the potential person idea, that being masturbation and condoms slaughtering potential people by the billion, it is in fitting with other accepted ideas. Few, I imagine who think purely in terms of the immediate loss of life if they were considering the destruction of Earth. Thinking about our progeny is totally rational. It's a bit of a mindfuck but that's how it is.
Why is the loss of sperm or eggs fundamentally different from the loss of fetuses? well, I suppose you could say, because there is zero chance of a sperm cell on its own becoming a human being. It's difficult.
Anyway, even though I don't like the pro-abortion arguments I agree with abortion because I think it's inevitable and if it were outlawed it would just put women at risk in the hands of back street "doctors". It is interesting how the whole pro abortion argument has developed though. It began with white supremacists and seems to have culminated in liberal intellectuals returning to accepting a kind of graduated level of importance of human life depending on the capabilities of the human.
Also, the way that it seems to be totally universally accepted that the father has no say in the matter is pretty shitty imo. It would perhaps produce a better society if they did, because it would mean every child had a father who truly wanted them.
