i suspect she's being constrained by the publication in not being definitive at the end, but this is nonetheless a decent summary of the right way to think about things.

this is strange language, but i feel i need to use it to get the point across: if a boy chooses to socialize with girls and rejects the influence of boys and men around him, his brain will feminize as a consequence of that choice.

the true challenge that we face as a society is in accepting these decisions.
