Queer people aren't one of those defined protected classes (because queerness asserts itself through behavior and action rather than being something intrinsic like skin color)...

In that sentence, I was talking about the current state of US law definitions of homosexuality as I understood them, wherein it seems like homosexuality is currently legally defined mostly as a set of actions and behaviors--whereas possessing a skin color, for instance, is not a behavior or action.

I did not mean to imply that that was my personal definiton or belief that homosexuality is either an action/behavior/choice or is somehow inborn or intrinsic.
