MY TAKE: The problem with many hollywood celebrities is that they are so intoxicated with fame they lose all sense of rationality and begin to behave like mad dogs

Honestly? The idiotic actor doesn’t deserve the dignity of a response from anyone -- least of all from Elon Musk -- but for the sake of understanding the man it must be pointed out that de Niro appears to have a very poor knowledge of history and worse, his antics suggests the existence of what is characterized as mental derangement syndrome.
