Because as we've said for a long time, the MAGA morons are basically fascist supporters. Trump managed to coalesce them into an active movement which have now taken on a life of their own now he's out of office. Just look at the support for Russia being given from the alt right in the US. Funny though, as shown on that Louis Theroux program, people like that Nick Fuentes (the young up and coming fascist star) and his mates are literally basement dwelling neckbeard incels
Even over here there is a strong correlation between being a Pro Trump, Pro Brexit, Anti-EU muppet and being Pro Putin. It's quite illuminating if you search on the forum for "Putin" or "Russia" and see what our resident fascist supportes have been saying over the years.
Here's a reply to someone linking up a video about "Putin acting like a Boss"
I'd vote for him all day long.
These useful idiots, and many others, have been spreading anti-west propaganda for years.
