what a weird hill to die on

if you dont mean to defend/apologise for musk. why did you even take the time to write this? As a german who studied the ns-regieme a lot in their life let me (and pretty much every expert on that issue who commented on that) tell you that this is a clear nazi solute. not greatly executed, the führer would have been dissapointed, but it features all the elements to that salute. as i suspect elon has a pr team, and ‘educated’ himself on the holocaust in Oświęcim, id say it is impossible he didnt know and accidentally mimiced it in that detail.
