Kuroki, people (especially girls) already spend enough time second-guessing themselves about whether they should really feel bothered or threatened. Sympathy for the person who's making you feel uncomfortable should not be a priority. You're part of the problem right now and you need to stop.
People have every right to avoid people they don't like. Ideally they'd have the gumption to tell these people directly, but if they don't...a girl should NEVER think that she has to deal with getting grabbed at, physically assaulted, before she can get help with her situation.
You're not good with women. Lots of creepers are also not good with women. That doesn't mean you need to be a cheerleader or speak up for these guys poor hurt feelings, it means you (and they) need to eliminate the behavior that makes them creepy.
