On the Internet, where people are anonymous, you are going to have more rude comments from men. The male of the species is hardwired to see women as sexual objects and while that doesn’t forgive crude comments it does point to their cause being an evolutionary fact. Men are programmed with a strong sex drive to propagate the species.
So men are, by their nature, sexually driven and hence crude. But that crudeness is already considered socially unacceptable and that’s why the great majority of men don’t make them. So having a "discussion on the topic" is stupid.
Because all a discussion would yield is the rational conclusion that crude comments are wrong which we already know and which won't stop those who make them from continuing to do so.
