The last one is the worst. The ones I see are the untagged ones that get past the filter. The characters are never canonically trans. I've dropped every work on the spot. Fuck that noise. Some authors have it as their "headcannon" and consider themselves above tagging. Those authors are blacklisted for me. If I ever get in a fandom again, I'm going to start leaving scathing reviews.

Another one I see is the super heavy handed monologue where a character suddenly starts giving a lecture on some social justice topic, like sexual consent, or slut shaming, or racism. I don't have to disagree with it to find it ridiculously over the top, ham-fisted, and out of character. If they can't handle these topics properly, I wish they don't touch it at all.
