The only way to do this is not to expect other men to speak up for you. Speak up for yourself if this matters.
I intervened while in college once. The guy was wolf whistling at woman after woman. None of them seemed to give him any attention. After a while I asked him to stop, that his behavior was annoying me. We very nearly came to physical violence. I was not armed with anything bigger than my books. It turned out that this guy had a cane due to injuries he’d sustained at a younger age. He was still quite strong in most other ways, though. Had it gone badly, I would have been beaten pretty severely.
The truth is that any man acting in this manner is doing so because he feels like a bad-ass monster. Verbal admonishment will not get you far, and could very easily get you hurt. That goes for everyone.
Now if you happen to be the supervisor, that’s a different issue of authority. Then you have cause and reason to admonish poor behavior that he will have to respect. But if you’re just another guy, you’re FAR better off staying out of the fray.
If you’re the woman who has to put up with that crap, I highly recommend taking self defense classes. Ignore the dick-heads if you can, and be ready to fight them if you can’t.
