Of course, intersectionality theory is a confused muddle. It fights racism and sexism by classifying everyone according to race and sex. It views race and gender privilege as the root of all evil, while ignoring the role played by dogmatic ideologies held by all genders. And it is unfalsifiable - to its adherents, criticism and rejection of the theory actually demonstrate its truth, by showing how deeply we all have internalized our oppression.

Young women at our elite colleges are among the safest, most privileged and most empowered of any group on the planet. Yet, from the moment they get to campus - and now, even earlier - an endless stream of propaganda tells them otherwise. They are offered safe spaces and healing circles to help them cope with the ravages of a phantom patriarchy.

Toy companies aren't interested in ideology, they want to sell toys. If they would sell a toy that both boys and girls would buy, it doubles profits.

Any child may go through periods during which they become less outspoken with their parents or teachers. But girls, like boys, live in many different worlds - they have their friends and their classroom and their parents - and within these different domains, they may have different levels of expressiveness.

I don't think anyone will deny that girls are academically superior as a group.

Trigger warnings and safe spaces are an infantilizing setback for feminism - and for women.

In reality, American girls are among the most outspoken, ambitious, successful girls in the history of the human race.
