This applies to things as small as being rude, to things as serious as sexual assault. If you want an example you need to look no further than the platform we are all on right now. If you look at their content policy you will see that in the very first rule they state that only "vulnerable" groups are protected. A Reddit Admin has even clarified that you have to make your own sub if you want the same basic protection afforded to everyone else.

When it comes to more serious examples you just need to look at how the news reports female predators. I'm sure we have all seen the typical headlines of female teachers that "had sex" with one of her students (we all know the headline would use a certain other word if the genders were flipped). There was also a recent example of a woman who was arrested for diddling herself on the beach (she was reported by a family with kids) and was later found to have taken her own life. If you look at the comment section you can see all sorts of "poor her" reactions, but something tells me it would not be the same if it was a man who got caught whacking one out in front of children.
