Because they are the people who have been made uncomfortable by his behavior. If it were men, or also men, I'm sure the parent post would have read "men or women". This is not an abstract case, so implying that somehow men are underrepresented when dealing with a person whose (alleged) behavior has been targeted at women sounds a little petty.

Imagine someone is accused of abusing children, and the local prosecutor says "if we find that any children have been harmed, we will press charges". Do you really think you need to correct them by saying "but what about adults?" It's unnecessary, and distracts from the actual case.
