so I found

1. "you have said the actual truth" reply to some guy about the great replacement thing or mass migration? which was then followed up with an apology and he said it was one of the most foolish things he's ever done.

2. said George soros hates humanity

3. compared Trudeau to a Adolf Hitler

4. some WW2 photo with a Wehrmaht soldier with a caption as a meme

5. mocking those who called him a nazi by saying stuff like "bet you did Nazi that coming"

considering all the other kinds of things he's done and posted on Twitter, I'm not convinced he's an evil nazi yet

For this to be 'sealioning' you need to assume Musk is a nazi and questions about him being such are meant to draw attention away from this 'fact'. Since Musk has - narrative notwithstanding - not been shown to be a nazi this isn't actually 'sealioning' nor any of those other Newspeak terms. It is a question for some actual proof - not more narrative - for the accusation made against Musk. Thus far such proof has not been shown, only more circular reasoning around the narrative.

I suspect all these narrative-followers actually realise Musk isn't a nazi but they just consider him to be someone who needs to be dealt with and as such are fine with throwing everything at the wall to see what sticks.
