Conpletely agree. Like you said, many people on Reddit are actually correctly calling him a he, but their comments are removed or heavily downvoted. I suspect that the only reason they aren't all being removed is that Reddit is already under fire for censoring-- if people unfamiliar with the transgender movement opened up those threads and saw a massive wave of "[removed]", they'd flip their shit even more.

edit: Also I appreciate you calling out the fact that a crime done by a man is being described as done by a woman. Gotta give credit where credit's due, lol. I would ask why they aren't proudly announcing his status as a transwoman but we all know the answer, haha.
