He does. This UK stuff has nothing to do with the UK, ironically.
As I've said in the past, I read everything. Far left, far right, centre, socialist, communist, capitalist, fascist, etc. It gives you a well rounded view.
Musk's comments/proposals on the importance of bringing in H1B immigrants to the US has created a split in the Trump base. They started doubting Musk in terms of his commitment to "America First" or the idea that the US shouldn't import more workers from abroad. Musk has attached himself to Trump in such a way whereby any reflection on him is a reflection on Trump.
He failed their purity test. So instead of trying to win the argument, he's done a few things including banning a ton of critics but more importantly has shifted the conversation away from his controversial ideas on H1B to "Muslim rape gangs". Of course he couldn't target the US with this for fear of being labelled a negative influence so he has dredged up some horrific events in our recent history, told half the story, and then the Trump base is back on board.
This is an extremely obvious play and I'm not sure why others cannot see this for what it is - it's an attempt to repair the fractures on the US right and has nothing to do with the UK in the higher level.
