Overall, I appreciate the point that you are making, but I think you underestimate the importance of people who were “merely” creeped-out by predators speaking up. Being creeped out is a legitimate and valuable visceral reaction to encountering someone who is a predator. Every woman out there, if you haven’t got one…

When someone just won’t leave you alone, especially someone who has said inappropriate things previously (in this case, AT WORK), it’s legitimately threatening. It ruins the party at best, and it makes you fearful for what might happen afterwards. “Insidious” is 100% the correct word. It instills dread.
