Yep, all very true.

I spent most of my childhood believing that homosexuality was unnatural, inherently sinful, and entirely unique to humans, because that's the spiel that the local Southern Baptist preachers were selling. The same is true for things we call "gender roles." Some male animals act in ways we once reflexively associated with females of their species, and vice versa.

I'll edit the comment to remove the reference to homosexuality, though, because that point wasn't especially clear or useful.
