Again, I do not wish to debate whether Musk is a nazi (literal or figurative). I don't own or use any of his products, and he is free to espouse whatever views he wants, as we all are. You are absolutely entitled to develop and hold your own opinions regarding Musk and I don't want to attempt to convince you to change them.
Where I both disagree and agree with you is your statement that "the subject is debated again and again each time it appears". This may be true in general, but my point is that here on HN, it has become a truism that Elon performed a nazi salute. My point is that you're right that other outlets present the alternative view that I mentioned above, but I'm not sure ANY substantive debate regarding this specific action ever happened here, and even if it did once, the fact that it has now been stated as fact that "Elon gave a nazi salute" at least twice so far in this thread without anyone bringing attention to the fact that others might disagree with that interpretation does not lend credence to Drew's assessment that HN has been overrun with right-wing bias.
