And I didn't say gender had anything to do with harassment. We're discussing the article, which happens to be written by a woman.
And just so I can get really pedantic: gender is inferred as a context of speech. If you are calling a cis-woman "guy" or "dude", it is inferred you are speaking colloquially. If you call a transwoman "guy" or "dude", it is inferred [by the subject] that you are mis-gendering them, and is offensive.
And more to the point of the context of the (now-deleted) comment: if you say "guy", "he", "him", and "dude" all about the same subject, you are calling the subject a man. You can't argue your way around blatantly misgendering someone multiple times.
When I was at my first job when I was 16, I had a female manager. I didn't think anything of it. Well, she had a thing for tall men (and high school boys). I wanted nothing of it.
So when she laid it on thick, I told her I appreciated the attention and compliments, but I want to be single for the time being. She didn't quit.
Well, she did it around the district manager. Fired on the spot.
