No, it's not, though I will cede that the distinction is a subtle one. My point is that their specific words are not important to them. They're just saying whatever. By the letter of the definition, it is sexual harassment, but by the spirit of their actions, it is not. And if you don't understand why someone is acting the way they are, you stand little chance of persuading them to change their ways. You can stand around and quote rape statistics all you want - it will fall on deaf ears. It has.
First you identify the real problem. The root problem is not that people are harassing women, the true problem is people are harassing people online. You can argue that you think it is worse when women are effected but that distinction does not get us closer to a solution and only serves to drive a wedge between people. Arguments about who is victimized more are useless.
