It depends on your definition of toxic and your definition of truth. The belief that categorical statements have zero relevance in this world is an ideal that is just too unlikely to be true. Broad statements can be made about both men and women.
For example Women tend to have bigger breasts then most men. Men tend to be physically stronger than women. Men tend to run faster than women. Women tend to be shorter then men. Men tend to weigh more than women.
These are all the same exact broad generalizations of the same nature that you pinpointed above but have the strange opposite effect. You say it is toxic to make broad generalizations but despite this you and most people would agree that you'd be insane not to notice the general differences in physicality I mentioned above. This is a contradiction.
Why is it when someone makes a generalization about the physical differences between men and women there is no resistance but as soon as someone mentions behavioral differences like how women tend to be attracted to stronger men that person suddenly violated a social contract?
It makes perfect logical sense. We see it all the time. Women are generally attracted to men that are stronger than them. There are tons of exceptions but the generality is real.
The delusion that's occurring within our society today is that although we are aware that biology can control physical differences between men and women by some black magic we cannot even fathom the fact that this same biology controls behavioral differences. No... biology must make men and women have the exact same intelligence and the exact same behavior according to current social thinking. Does this make sense from a logical standpoint? Again... No.... So why do we delude ourselves with this false notion?
We do it because we are afraid of sexism and racism. We are deathly afraid of inequality even though logically inequality is biologically built into us. No one is actually created equal biologically in terms of intelligence, behavior and physicality. It goes against everything we know about biology and natural selection. In order for something to be naturally selected it CANNOT be equal.
What is toxic is the attempt to paint a pretty idealistic picture of the world at the expense of truth. Equal rights for all does not mean people are born with equal biological traits.
Don't let an ideal hide the reality of the world we live in, but also don't let the ugly reality of the world pervert your ideals. We must learn to coexist with the contradiction.
