To paraphrase Dr. Brett Weinstein, who actually is a biologist, what sex commies call “gender” is essentially the same thing as what biologists call “sex roles”. And it’s seen throughout the animal kingdom that male and female animals will behave differently and perform different tasks. For example, there are species of birds where the female will incubate the eggs and the male will bring food back to the nest. So the fact that men and women naturally gravitate towards different careers or different chores/tasks within a relationship is entirely expected. So when you see feminists tell women to act like men or trannies tell mentally I’ll men to act like women, it’s just the usual commie tactic of fighting against reality itself once again.
