I believe this comes from people trying to show off their education. Traditionally, words with a french descent were pronounced with a silent H. So for example hospital (from French hôpital) is an hospital, where hound (from Germanic hund) is a hound.
This is pretty much deprecated these days and anyone enforcing it is beyond grammar nazi, but it’s interesting to know the pattern.

Hanlon’s razor dictates that we should not attribute to malice that which can be attributed to incompetence.
So, by posting this response, you are very, very stupid. You are incompetent of understanding the fundamental difference between the VIDEO of Elon saluting Adolf Hitler, and the IMAGES of all these people waving.
If you respond to this, you’re showing that you have enough intelligence to understand the difference between Elon’s gesture and a wave, so you’re therefore defending his sieg heil and you remove all doubt that you are a Nazi, and therefore unwelcome here, or anywhere.
I guess you have a third choice of claiming it was a joke or a shit post or whatever.
