you again extrapolate “women on an average may be better at taking care of young children” to “men are unnecessary” which is far more than exaggeration, dont u think? and perhaps speaks to some of your own past experience / insecurity or circumstance where people around you felt / made you feel that way - pure conjecture here but possibly a reason (which is horrible if they did because you or most men I believe are and should be very necessary parts of chidlrens lives)
