Do the men who get looked at like that fear being raped? Do they fear leaving the building thinking that the women will be out there ready to attack them?
Or do the men being looked at by older women get their egos puffed up by it?
Do they fear being unwilling objects of sexual advances?
Do they fear for their safety? Do they try to figure out how to get to their cars after their gym work without suffering unwanted advances? Do they fear what the women will do to them if they reject the women?
Or do they brag amongst themselves in the showers afterward.
THAT is the difference. And it's a HUGE difference.
It's about POWER. In general, men's bodies are much more powerful than women's. Men's bodies present greater DANGER to women.
Your belief that these are the same things is completely unfounded. It demonstrates a serious lack of thinking about the consequences to men vs the consequences to women.
IT. IS. NOT. THE. SAME.
