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.

Says somebody that has clearly not seen the news.
ICE isn’t the one killing unarmed women?
I’m not even in the US and people tried to spread the “on-duty government agent protected himself against the motorized domestic terrorist” narrative here. It seems to be all over there.
Yes, and the meme is reinforcing that narrative.
The meme is making fun of ICE agents for apparently being such cowards that they are afraid of an unarmed woman, seeing her as a threat on the level of Darth Vader.
It’s emasculating them.
It’s making fun of them by just… repeating their narrative?
In a way that makes the narrative look dumb, yes
And what way is that? Because it seems to me like just repeating, not satirizing or parodying.
I think you’re just not catching it, which is perfectly fine.
Memes are simplified and therefore you can put more (or less) into them than the creator intended, so there’s always multiple ways to interpret them.
My interpretation is this: If a perfectly regular, unarmed woman is that dangerous to them, then that makes them absolute cowards, and completely worthless at their supposed jobs. It also shatters any narrative about them being tough in any way, which I do believe is how they perceive themselves.
