Yeah, I don't agree with this person's methods, but it does kind of prove their hypothesis (somewhat): violent content can still be upvoted in trans communities, and that trans identity acts as a shield for bad behavior. If you look carefully you'll see that a lot of this account's posts were not upvoted and some were strongly downvoted, so the outcome of this "experiment" is a bit more mixed than the author is asserting. However, it still does prove a point.

Although I can only speak for myself, I don't think those of us who were following the user account saw it as typical. It was more, this person is obviously a threat and why won't anybody say anything about it? Again, the point is not that trans people are all this bad (I believe most trans people are OK, especially if they are not making ridiculous demands). However, the trans ideology, in its current form, does allow a monster to hide behind a trans identity. It just so happens that this particular monster was not real.
