My initial comment asserted exactly one thing: that TADC has simplistic writing and that younger people probably appreciate that.

Sure let's check that.

it's also very much "baby's first character driven story". A lot of scenes involve the characters spelling out their feelings in no uncertain terms which, if your media taste is still at that level, reads as really deep and interesting

Hmm. And then as for "After that, people started swearing at me, which is when I asserted that people shouldn't limit themselves to just watching simplistic media", someone very justifiably told you to fuck off for that very backhanded sanctimonious bit about "if your media taste is still at that level", you responded with "idk how old you are, but a millennial should be consuming media more challenging than TADC. Tell me I'm wrong." which is very much NOT just saying people shouldn't limit themselves to simplistic media, and is entirely rendering judgement.

You are in your 30s, you should be consuming more challenging media than TADC. That shit about cartesian dualism or whatever is fucking cope about a plotline that's one step removed from Sword Art Online. You are what people are talking about when they complain about emotionally stunted adult children.

and THAT is where the ableism comes in. This has nothing to do with "exclusively consuming children's media" or "limiting themselves to just watching simplistic media". I frankly do not care how frustrated you are at someone for committing the high crime of telling you to fuck off, you don't get to pull a Vaush and start spewing reactionary dogwater just because you deem the other person bad.
