Wojak originated on 4chan in the 2010s as a simple reaction image before being associated alongside pepe as a foil, the pepe was often a self insert and the wojak was a strawman. However the memes changed and eventually wojak outgrew pepe in popularity and memes started to focus exclusively on wojak. Wojak as a character is not cool, is not a self insert, and is often used to mock a group of people by portraying them as cringe. Wojak is the perfect strawman to internet fascists because it's emotionless, it's white, and it's weak. Marginalized groups like gays and vegans and leftists are often portrayed as wojak because the fascists need to make strawmen because if there isn't an enemy the whole ideology falls apart. That's not to say the left hasn't been using wojak in a constructive manner, but it's merely appropriation. Wojak had always been reactionary while pepe was only adopted by the right, wojak was born by it. Now I'm asking you to read a rage comic, or several. Compare how much racism and sexism and reactionary politics you find those outdated memes then look at some wojaks. The best way you can learn how bad wojak as a meme is by looking at it from a critical lens. also literal nazis made a cartoon series with wojaks
Not to be a debate bro who brings up fallacies, but one thing I see plaguing the online left a lot is genetic fallacy. A lot of people around here and elsewhere seem to place a lot of virtue around somethings origin rather than the context of its current use. I've seen a lot of weird ass struggle sessions about the original bourgeois or proletariat character of various activities from golf, hiking, using various kitchen appliances, pet ownership, beer drinking, what have you, with no consideration to it's current context, and perhaps more importantly, no consideration as to whether this fucking matters? Just because rich people like something doesn't mean it's bad, just because working class people like something doesn't mean it's good, the point of socialism is to end class contradictions not hyper analyze to figure out how to be the "most worker".
Sorry got on a tangent there. But yeah we do seem to place a weird amount of value on the origin of something rather than it's current context. Like fuck I wouldn't be surprised if it turned out some cure for cancer was invented by a Nazi half the people here would refuse to take it even if that Nazi has been dead for decades and it's 100% confirmed to work.
I think that kind of over analysis mostly just stems from middle/upper class guilt a lot of comrades from wealthier backgrounds feel. It's very much not necessary though, similar to the point you made, a persons background is fairly insignificant vs what the actually do to help.
