The association of "Aryan" Germans with being shredded and people who are trans, autistic, etc. being positioned as the opposite. Eugenics is the idea that some people are genetically "superior" to others, making "Aryan" babies was a big part of it, but that's the main idea being referenced.

As somebody who is autistic myself, it doesn't feel right as a "joke". Yes, it paints people who believe in that sort of thing like idiots, because they are, but this is programmer humour, jokes should be about programming things! Off-topic and generally unfunny in my opinion.

You are right. It’s still a meme which uses the image of a buff guy who wouldnt code without ai.

I guess most lemmings who code are not a buff guy but the trans-puppy.

Else I don’t understand another angle why some people are offended or otherwise downvote this

Def misread it on first pass. Thanks for straightening me out.

Yeah, OP did not do a good job with this one.

A lot of them yes, though there are exceptions. You can find the odd "neurospicy" trans person using AI, though most are instead cis neurotypical people, most of which suddenly become less empathetic towards others the moment they start using genAI.
