"R U TRIGGERED" and all its subvariants were radioactive toxic waste and turned a valid and important psychological concept into bullying vector that for a time had nearly universal acceptance.
I still see vestiges of "le epic bacon" out there but it's mostly confined to aging :grillman: types and some :up-yours-woke-moralists: cultists and a few contrarian carninist edgelords that want to "trigger the vegans." Yes I know all of the above have a lot of overlap.
In the Dawkins sense, yes, correct, they're all memes, and as morally and politically neutral as an empty cup. They carry a message. It could be some racist bullshit, or it can be :wojak-nooo: CONTROLLERCELS MALDING OVER ALPHA CHAD KEYBOARD AND MOUSE USERS :gigachad:
Not that some messages don't have a preferred means of delivery. Like, the empty cup can still have a swastika on it. But I don't feel that the virgin/chad is that. It's just so inherently silly that nobody but a fucking moron could use it completely unironically.
(Also just to be obnoxiously pedantic "propaganda" technically refers to anything created with the purpose of dissemination so yes memes are propaganda and propaganda is memes :very-smart: )
