@Mr_NutterButter women not being able to vote is a pretty big cultural change in of itself, but let's use abortion laws as an example. women being able to vote is pretty much the only thing keeping the pro-choice thing afloat. if only men were able to vote, it's pretty likely that restrictions on abortions would get a lot heavier, and punishments for the ones performing them (or potentially even getting them) would increase. that would change our culture for sure.

there are other things that women vote on more than men too, even if only by a small margin.
