I'm not really sure what you're trying to insinuate with this. Is there a cabal of far right extremists acting out some coordinated plan? Honestly that isn't the point, 'though there is some evidence of it - see Steve Bannon. The point is surely that all the characters you list have several traits in common. These are, inter alia:
- mendacity
- amorality
- opportunism
- self aggrandisement
- malignant narcism
They manifest as rightwing populists taking cues off each other because there is a gullible population out there that laps it up.
Why do you think Johnson suddenly discovered the repetition of rightwing conspiracy theories as a deflection tactic? That's straight out of the Trump playbook.
