If women were automatically supposed to want kids and be mothers than 1) women who don't want kids wouldn't be a thing 2) postpartum depression wouldn't be a thing and 3) mothers who abuse their kids wouldn't be a thing.
Women are biologically able to have kids but that doesn't mean every woman wants or needs kids and it doesn't mean she's automatically fit to take care of kids just because she has them.
Most dudes can barely afford kids anyway, so that should be a +++ for most you dudes.
