It’s just whataboutism to defend musk and muddy the waters on what is actually fascist.
You can take a still frame from a number of movements to make it appear as if someone is doing a Nazi salute.
For example Mamdani is literally just waving, but with a still frame from one specific angle it looks like a Nazi salute.
Compare that to musk where the whole video in context shows a clear Nazi salute.
Not every raised arm is a Nazi salute, but Nazis like it if you think that to be the case.
