I'm Starting To Feel Like The Reason Why So Many People On Tumblr Have Such A High Shot Dog Response

I'm starting to feel like the reason why so many people on Tumblr have such a high Shot Dog Response to everything they see is because they're trying to fit a nuanced worldview into an all-or-nothing brain, like shoving to a square peg into a round hole.

So while they understand that the "all X is Y" world view they've been taught is wrong, the concept of "not all X is always Y" is far too complex for their little brain, so it gets simplified into "no X is ever Y", and that's the stance that they are going to defend to death from now on.

Like they'll scroll through tumblr and see someone's post that's like "the bus driver that drives my route every morning has shaved his big moustache so for a second I didn't recognise him" and the thought process going on in their little brain is

Bus driver=he? He/him=male pronouns. All bus drivers ≠ male.

And the outraged reply they jump to is "how dare you assume that your bus driver was male just because they had a moustache, maybe they are nonbinary, nonbinary people can have a moustache without you assuming that they're male."
