Even if they started it that doesn't make the template or the memes made from it Nazi propaganda. A meme about baguettes and wordplay doesn't have much to do with Nazis...
Yes it does. It absolutely does. When you use their formats they get to use that as part of their recruiting.
It's like what happened with the trollface. Actual pedo rings use the widespread use of the troll face (which sampled "r--- rodent" in its design) as proof that their movement is popular when it's anything but. Plus it comes with the bonus they can dogwhistle with it and the average person won't catch on because they only see it as 'ha ha that funny troll face meme' It's also the reason the fake left (La Rouchites, aka destiny/vaush types) uses wojacks and peepee frogs "ironically" a lot. They get to pretend they're leftists while pushing cultural fascism.
Don't use nazi meme formats. You are helping them gain cultural relevance. Use literally anything else. If the underlying humor is actually funny the joke will land equally well if not better. EDIT: Yeah about the response I expected.
