You watched the actual video clips of those other still photos? And compared them to the actual video clip of Musk? And you still think "people see what they want to see"? So, a still photo of someone waving, compared to a video of someone slapping his chest and thrusting his hand out palm down are a matter of perspective to you? Seriously?
Exactly. The salute Elon did was a far cry from the hand waving by the others. One was an intentional salute and others were just garden variety hand waving. If someone can't tell the difference, they need help.
Whether it was intended to be trolling or a real salute is not really relevant. What's clear is that it was a purposeful act by Musk.
