@yaxu I'll take this thesis one step further and remove gender from the equation. People who tolerate bad behavior will stay and don't tolerate will leave regardless of gender.

However, as long being a bully and pushing people around is expected or supported for males (since we think it's what makes a man a proper man), these spaces will be dominated by males. Pushy, aggressive males.

...and this kills all collaboration and good things which come out of it.
