The UK Gov actually has an overview for you to inform yourself as to what they consider far right:

(The report itself doesn't do a particular good job either as they use some dubious sources and I don't agree with half of it, but their definitions of the groups are close enough).
I've listened to a lot of Weinstein on various shows he has appeared as a guest on and I haven't heard anything that can be considered far right. One of the first times I seen Weinstein was when he appeared on Dave Rubin who is a gay liberal/libertarian (the last time I watched his show it seemed to change every other week) that lives in California.
> Perhaps you could be excused for believing someone isn't far right when the overton window among english-speaking countries has narrowed so far to the right of center.
This is a complete nonsense. The Anglo-sphere for the most part is pretty much centre, centre-left. Many conservatives and paleo-conservatives complain their conservative parties aren't really conservative (which isn't far-right either btw).
The term far-right in itself is a poor description. A better term is a "reactionary right". But that is a whole other discussion between the "reactionary right" and the "traditional right". Right and Left are really poor descriptions of political positions and that is why many tests online now are multi-dimensional.
