I think it's more than just a few and I think she's trying to broaden the scope by showing (fairly clearly) that outside of the BSD community these issues are pervasive.
Hard for me to judge if that's true or not but I'll take her word for it.
A good friend of mine is biologically male, identifies as female though. He was public about that online and also due to other circumstances attracted a dedicated abuser. That abuser is so perfidious and persistent, that he (we assume) still manages to rally communities against my friend several years after it started.
I don't want to presume too much here, but my question is, if your friend identifies as female, and you're aware that she does, why do you refer to her as "he"? From a lot of your comments I get the impression that you're not very aware of feminist issues in general, but even without that knowledge, doesn't it seem disrespectful towards your friend to call her that? If she identifies as a woman, why call her something she's not? If who we are is in our minds, why should the body take precedence?
I could say a lot worse, certainly, since I'm a trans woman myself. I know firsthand what it feels like to have people deny your identity day after day (really shitty, to clarify). Even so, I'm trying to at least be understanding here, rather than give a knee-jerk reaction.
