It is much more productive and useful to try to understand people's concerns but it is also not as easy.

This is true but this is not what's happened here. The discussion is about whether Musk's gesture is a Nazi salute. OP called ignorant people who do not see it as such. They said nothing about those people's opinions and did not accuse them of being far right or Nazis themselves. In fact OP didn't even call Musk a nazi in their post. To conclude that it was their hidden intention to do so is a leap in logic that is not obvious.
The whole "it is wrong to observe peoples politics and behavior and call them what they are" thing was already absurd, this is really stretching it.
Given how tense the current political climate is, it's all the more important to avoid resorting in using fallacies. Name calling is one such trap, and misrepresenting one's opponent's arguments is another one.
Also it‘s a difference to be against immigration versus the open salutation and worshipping of a mass murderer millions of europeans and americans have died for to stop.
For me it’s disgusting that this tabu is now broken and everybody still tries to loudly ignore it!
