Though I'm sure right-wing groups believe themselves to be tolerant of one-another and their allies and others with similar aims, and that groups that oppose them are intolerant and therefore must be met with intolerance. The paradox of the paradox of tolerance is that you can't claim tolerance by excusing your intolerance with the paradox of tolerance. Or said another way, one man's tolerance is another's intolerance.
This is not hard to see unless one is being willfully blind. Which is especially funny given this conversation is happening in response to giving Grok an intentional blind spot.
The mythos of the liberals is way more personnalized, usually assigning moral failings to people who disagree eith them, something like "those people are dumb enough to be manipulated, we ought to explain thing slower/better" "we are on the reason's side". The fondamental attribution error is probably the fallacy for which liberals (authoritarians liberals especially) are the most susceptible to.
For the leftist movements, the mythos will either go to a marxist or neomarxist "We oppose the billionaire/landlords/owner class, and must struggle together to put it down, educate yourself and those close to you" or to a more generic anti-system mythos.
Furthermore, the left is often egalitarian, and the "traitor in our rank" mythos is mobilized to explain why you are not above X depite being (genetically for nazis, culturally for fascists) superior.
Seems really difficult to quantify to the extent you can just say they don't. We can all come up with examples or handwaved anecdotes of any kind of enemy from any ideology really, so what actual metrics are you using to differentiate these things?
I'm not sating paranoia isn't present everywhere, i'm saying one one kind of political ideology use it as a building block of their ideology, and it is fascism.
"We are (culturally/genetically) the best, but right now others seems better/won/took advantage of us. The only reason we are not at the top is because we have internal traitors (jew/blochevics/unionist/homosexuals/whatever float your boat). We have to eliminate those"
Each time something like this is uttered to justify taking power away from court/parliaments, you'll be looking at fascism. Which can be used with capitalism or with communism (as production methods). The "internal enemy" as a reason to justify taking power away from the court/ignoring human right/taking power away from parliement is fascistic. [0]
That's mainly how i differentiate the extreme centre from fascists, their justification. Von Papen/Schleifer removed power from the Weimar parliament because "people are dumb and did not understood how intelligent we are, so we can safely ignore their vote", then Hindeburg installed Hitler, who did the same thing, but stronger, and justified it with the "internal traitor" myth.
[0] Trotsky called that "bonapartism", and argued that Stalinism was another heir of that ideology, but here, i think he is simply wrong (as usual), although it is interesting (where lie the fascism roots?). And now, writing about it, i will have to re-read him and think about it more, he might have a point, is fascism an evolution of bonpartism, with a more rigid hierarchical order? :/ fml.
