He tweeted "pedo guy" in response to the diver saying to "stick his submarine where it hurts". I don't see it as accusation as much as I don't see what the diver said as an order given to Musk. Both were just insulting each other.
Lol, a random person sharing their obvious opinion about ethics of eating meat is totally, undeniably different than one of the world's most powerful men legitimately and honestly accusing a rescue worker of being a pedophile.
No one is going to get investigated or have their careers ruined because a vegan called them a murder, obviously.
Unreal what sort of knots someone will tie themselves into to excuse this type of behavior.
