I think you’ve hit the crux of the issue here - memes are never going to reach people the way IRL organizing can. It’s not that we’re writing off people who can’t engage with theory on their own, it’s that we have to go meet them where they are.

In the context of this specific meme, I don’t think we’re discussing the disaffected members of the working class, but those who describe themselves as liberals - those who fetishize law, read The New York Times unironically, and worship Obama. Those liberals tend to be more educated and are definitely capable of engaging with theory; they choose not to because it threatens their entire conception of the world and their place in it. They present themselves as caring about social issues less out of a concern for their fellow human beings and more out of a self-concept that they are “good people” - they are idealistic through and through, though they may or may not be religious. Their ego is caught up in being an “upstanding citizen” or having some sort of moral fortitude that may belie what they actually believe about the people around them. This is why when they are pushed about the contradiction (the “scratched liberal”), they will lash out and reveal the true face underneath - one of self-interest and a desire to be better than other people, which will dovetail quite easily with fascism the moment fascism is seen to be socially acceptable.

Some smaller number who self-describe as liberal may just need a push in the right direction and are merely suffering from the miseducation prevalent in the west, but these are generally not the ones cheering for the US Democratic Party or arguing about the “rule of law” online.
