Here in the NYC metro area American children are becoming rare; the open borders and resettlement of foreigners here is mainly to address that (many of our schools would close without imported students). There is also no shortage of childless people pushing dogs around in strollers.
I believe more men are getting vasectomies, but I don’t think it is “to protest overturning Roe”; I believe it is much more likely that due to the legal and financial implications of the gender wars they see a convenient excuse to implement what many men have been doing for decades now: cohabitate without breeding. I don’t know if this country has ever seen such a high percentage of childless American women wishing for children, or childless American men determined to avoid them.
I wouldn’t want to be a young, man today or an older one. Five years ago, I told my son to beware of young women these days. When he stopped pursuing the teasing vamps, and found someone wholesome, full of kind femininity and a stable family life is when he found happiness two years ago.
