Humans have been around for some thousands of years but is it just me or is there some giant conspiracy to hide female nature

men 9000 years ago must have known woman were not worth trusting but some where between now and then they just started lying about how great mothers and women and how benevolent woman are it makes no sense it's like trying to convince society rabbits are elephants why did men up and decide to do this? religion says they can't be trusted so does statistics why did men decide to call them the fairer sex and stuff is it really just because of simps?
