Surreal humour (also called surreal comedy, absurdist humour, or absurdist comedy) is a form of humour predicated on deliberate violations of causal reasoning, thus producing events and behaviours that are obviously illogical. Portrayals of surreal humour tend to involve bizarre juxtapositions, incongruity, non-sequiturs, irrational or absurd situations, and expressions of nonsense.
Here the meme artist is highlighting the nonsense statements by ICE, the DOJ and the Vice president of the United States of America, J.D. Vance.
I think what's happening is one of those situations, where you can put more or less into a meme due to their simplification.
I think you're being very literal with it, and trying to cross-equate more of their narrative to the meme than the majority of people.
The ICE being labelled as an actual nazi, being a pretty big sign that it isn't supporting their narrative.
Most people read it as a satirical take on ICE's narrative, that obviously does not match reality. The satire is evident enough to everyone else that the meme does not enforce the fascist narrative.
If the meme was flipped as you suggest, it would just seem tasteless and unfunny (with humour being the main point of memes), and seem to glorify ICE by making them appear to be actually powerful, and not the scared little, emotionally stunted boys they actually are.
I think it's fine if you don't get on a comedic level, and if you think it's a bad meme, then that's fine too. Memes are simplified by their nature, and we won't all enjoy the same ones.
I'm going to exit this discussion, as I don't expect us to find any real middle ground, or for there to be anything further for me to learn. Besides, it's a discussion about a meme, so it's not exactly important. I hope you have a great day though.
