"Girls mature faster," "women have superior immune systems," "men are less valuable because in the unlikely event that there are 100 people left on Earth then one man could impregnate all the women," "women are more emotionally intelligent," "we evolved to value female life over male life."

All of these are things I've seen written unironically all over Reddit and, disturbingly, in men's rights spaces. They represent a position of female biological superiority that I think needs to be addressed and snuffed out. Some of them are just plain wrong, others represent a misunderstanding of statistics and of science. None of them are true as stated without clarification.

Some people even go so far as to advocate for practices such as "red-shirting" which would mean holding all boys back a year in schools. Can you imagine telling boys this? "Why is twin sister a year ahead of me?" "Because she's a girl and girls are better at school." This falls under the category of being a misunderstanding of statistics and science. Boys and girls do follow different developmental paths, but the average boy and the average girl are well within one standard deviation of one another, regardless of what you decide constitutes "maturity" (of which the measurement itself is often chosen to align with stereotypically female behaviors).

I can elaborate upon request, but I want to start this discussion. Why are these things so often repeated in the spaces that should be dedicated to dismantling these sexist misconceptions? And what rhetorical tools do we need to bust these myths? Studies? Would plots of nearly identical (but shifted) normal distributions help? Impassioned pleas for reason?
