I think these two quotes get at what I feel is one of the worst things about this kind of situation. Whatever the victim/target of the inappropriate behavior does in response, it’s wrong. It’s too passive, or it’s too aggressive/attention seeking. It’s overreacting or underreacting. And somehow it’s a much bigger deal than the original offensive behavior. The target of the harassment is held to an impossible standard of perfection in their response, while the harasser’s much more inappropriate behavior is either largely ignored or outright disbelieved.
Like you with the face, I doubt that speaking up in the moment is really going to make much difference to someone who is deliberately groping coworkers. And if the touching is truly accidental, the touch-er is not going to be spared any embarrassment if the touch-ee loudly says “Hey, get your hands off me!” in front of a bunch of other coworkers rather than quietly taking the matter to a superior.
I’m generally in favor of the touch-ee speaking up in the moment mostly because I think that otherwise s/he is likely to be very self-critical (“Why didn’t I just say something?”) later. But I don’t think the targets of unwanted sexual attention are under any special moral obligation to confront the touch-ers. There will be times where doing so would only escalate the situation, but more importantly, the REAL problem is that inappropriate touching was happening in the first place. The victim certainly shouldn’t be faulted for being uncertain, confused, frightened, or angry. Not everyone is going to transform into a hero the moment they become the target of inappropriate behavior, and it’s ridiculous to expect that they should.
