It seems that Elon Musk's fascist salute, is an expression of Musk's involvement in European nationalist and xenophobic politics in EU and UK.
(In US Musk is pro immigration, but it n UE, UK is against, strange)
What is interesting is that nobody from Trump administration doesn't stop him
Brexit has destabilized Europe. The old was held together by cooperation of 3 former enemies: UK,France and Germany.
Aggressive involment of Musk in EU politics, and the fact that Whitehouse or State Dept doesn't reign him in, will deepen divides between US and EU.
Which will be the joy of Beijing who tries for years to woo away EU from US .
I wonder what is happening with Tesla factories in China.
