Elon has basically been a 4klan edgelord for years now. Since he brought Twitter, he's been signal boosting and outright agreeing with neo-Nazis on his personal account. The entire reason for his previous interaction with the ADL was because he openly agreed with the great replacement theory.
Sure, he did a little disingenuous pro-Israel PR after, but this was before he was shadow president.
Considering his recent history, anyone who is foolish enough to see Musk's clear-as-day seig heil and think it's just an awkward or autistic gesture could probably be shown a picture of Epstein hugged up to a 14 year-old girl and be convinced it was just some innocent, non-sexual display of affection.
