The problem is that those arguments are not falsifiable. If not one, but two completely reasonable explanation cannot convince you of someone motivations, nothing can. However, I don’t care if Musk did or did not a Nazi salute. His actions speak much louder (in a bad sense) than the aesthetic that he decides to adopt. Proton donation pattern for example would be a strong indicator to measure intentions.
but it was a wildly tone deaf one if so
Maybe. But also maybe people are allowed to have different cultural references, and in a global context (i.e., the internet) we should expect diversity. I - for example - had never heard of this 88 thing, and I would definitely not think about it at all the next time I create a username, and I didn’t think it when I went to a barber shop that has that number in the name. Likewise, I wouldn’t call anybody writing “Merry Xmas” tone deaf for missing the reference to the X MAS of infamous history (and just recently in the news). For some people it’s apparently impossible to see their culture as non-universal (at the cost of sounding stereotypical, folks from US have particularly this problem after decades of cultural hegemony).
for a party that’s steeped in all of the same memetic game playing, you cant ignore the dog whistles
This all happened before Musk/Bannon salute. Just to specify it.
I agree with you on the principle. In this case I disagree with the premise. Years of actions I think easily out weight that tweet. If that’s the only reason to be suspicious, then I don’t think it’s warranted.
