Blonde vs. Gay

On the question of "orientation" vs. behavior, not to mention whether or not DNA is destiny, if we may sideline Ms. Clairol for the sake of discussion—it's still all so confusing in this modern age. A friend wrote:

I think that the parallel between blond and gay fails, at least in part, because
being blonde doesn't have any behavioral component.

Not so.  It's well chronicled that two blondes died in a drive-in theater. Turned out they went to see "Closed For Winter."
