>>280071689 (OP)Because in a high trust low crime society very very very mild sexual harassment is seen as less bad than rape, but in decaying societies they get blended together into all being the same worst crime ever, since they become so common, and they escalate into rape so often. The West had a similar attitude towards pinching women's bottoms in the 50s. It was considered bad, but not giga ultra mega evil. Both Japan and the West eventually paid more attention to women's discomfort, and so these sort of things began to blend together with worse sexual crimes.
In an older show, a character committing mild sexual harassment is a sign he's a goofball who's rough around the edges, not a sign he's morally indefensible.
