"...defended things like groping as inevitable because according to him, men are designed to be sexual aggressors."
This can be debunked in the same way that drunk or "provocatively dressed" women are 'asking for it' can -
The implication that men can't help themselves, that they're either programmed or helpless in the face of an incapacitated woman, would mean that more men would be doing this to even more women.
Most men don't grope, assault or rape women, no matter how easy it would be for them to do so.
Only rapists rape, only gropers grope. Rinse and repeat.
