Now, when the far right, the actual far right, fucking nazi saluting far right come along, we have to ask, are they really far right, or is this just another attempt to shut down rational, polite conversation
I'm not sure how more far right you get than Nazis or Nazi sympathisers. These people want mass remigration programmes in Germany and use Nazi slogans while campaigning. They have been classed as an extremist organisation and associate with far right groups.
I don't think someone like Farage is far right, he's a right wing populist, though I can easily see how his anti immigration stance and other rhetoric could easily slip into the far right spectrum. He uses dog whistle politics, I've heard him use some far right phrases but he's very clever and has never been explicit.
However he does support dubious people such as Putin who he openly admires, Enoch Powell and has expressed sympathy for Andrew Tate. The problem with someone like Farage is his ability to draw the Overton window towards the far right.
