"Ladybrains" eh? So that's why women shouldn't be in STEM fields, and shouldn't be the leaders of companies, and shouldn't be in polticis - it's because they have "ladybrains" and are just naturally unsuited to it!
Because womanhood is really a state of mind, and it really is all about how well a person conforms to social sex-based stereotypes like chicks being naturally subservient, sensitive, emotional, and getting all of their fulfillment from serving other people and making other people happy. And manhood is all about being decisive and dominant and loud. Yep. It's all psychological. Girls are just naturally sweet-tempered and boys are just naturally into roughhousing.
How do you know there's not a teapot orbiting Mercury?
