Also, I don't know if anyone else here has browsed /tttt/ much, but I noticed that they are constantly validating non-binary identity as long as the term "non-binary" isn't used in the process.

I can see them say things such as:

"I wanna go on HRT, but I don't quite feel like I'm a woman, but I do wanna be more feminine than my male self!"

"Oh, that just makes you an HRT femboy."

"I'm a trans woman, but I don't mind people calling me he/him pronouns sometimes. What's up with that?"

"That just means you're based and don't seethe over misgendering, unlike those crybaby trans people who don't pass!"

And of course, posts like the one you put in OP are another example of this.

I literally relate to both sentiments that I gave in the quoted section, as well as the post in the image, but if I added "Oh yeah, and I identify as non-binary to convey this.", most /tttt/ users would be livid.

Hell, I even made a post about how I identify as non-binary, explicitly mentioned that I'm AMAB and that I'm on HRT, and I got multiple replies about how I'm a quirky teenage Tumblrina cis girl pretending to be trans for attention like they saw the word "non-binary" and neglected the rest of the post as soon as they got to that word.

I've concluded that it seems that they hate the word "non-binary" because they associate it with "cringy Tumblrina AFAB trans culture" rather than having an issue with whatever non-binary identity may manifest as in practice.

Thank fuck I stopped browsing /tttt/ and 4chan as a whole entirely.
