My question to pro-choice supporters

[Thumpalumpacus]

Children need support. Nature doesn't really care about de jure legality, but I suppose the only real answer would be a precoital agreement, in writing, signed by both parties.

That's exactly what I was thinking. If the law allowed for men to just opt out, I'd require a signed agreement from everyone I have sex with. Kind of a mood killer if you ask me.

Doesn't have to be. The discussion and agreement could happen entirely separate from the intimacy, seems to me, just as a prenup is made well in advance of vows.

ETA: Note that in my previous post, I meant to write "equality", not "legality". I have edited it to that effect.
