I'm confused.
I don't go up to women with children and advise them to give them up, but having chosen to be childless means I'm regularly told I'll never be "complete" unless I have a few kids and that no one will care about me when I'm old. It's annoying, but not a big deal, since the society I live in doesn't force me to have children.
The society I live in does try to force me not to commit suicide, so hearing from people on a pro-choice forum that I shouldn't kill myself because of their feelings/convictions sounds seriously unsympathetic and disappointing. They should be supporting me, not upholding laws and restrictions that force suffering on people.
No one who's posted on this thread can *make* you stay alive for the sake of your children, or make you "unhave" them; they're just expressing a viewpoint that doesn't have to matter to you; antinatalism doesn't apply to you when you've already got children. It's insensitive and rude to negate your choices in two areas at once, and it must be maddening as hell to encounter it on a pro-choice forum, but it doesn't actually make any difference.
Things that make a difference are making sure your children know they aren't guilty or inadequate. Making sure they're raised by someone who will be good to them. Making sure they know you care about them.
