It used to be that females would slap a guy who grabbed their ass, not just look awkwardly uncomfortable, and society accepted that as just. It was physical. With a slap she in no uncertain terms made it clear that she didn't want his advance. The whole matter was resolved with an even exchange of violence, not this extreme, feminine reaction where someone's life is destroyed from an inappropriate touch because nothing is more henous to a female than an interaction with an unworthy male.
