Looks like another misapplication of 'spectrum' where the intended term is - I assume - 'continuum', with 'left' wing' and all associated - 'beliefs about the world around them: their religion, their politics, ethics, hierarchical beliefs, resistance to change, thoughts on authority, tradition, etc. All combined contribute to where a person sits on the spectrum.' at one end and 'right wing' with ditto at the other end?

Look, there is no person in the world with an entirely identical 'set' of beliefs as any other. People often agree on some points and disagree on others. Not everyone of a particular religion are of a specific political leaning, to take one rather obvious example. Even within any religion there are schools with different beliefs, tendencies, leanings, and even within every school there are schisms and differences of opinion, and even within every person we change our minds from time to time.
Your definition of far right is attempting to create a Platonic ideal of a far right supporter. It might be an interesting thought experiment, but it's almost guaranteed to be proven wrong as soon as you try to describe it, because the basic premise (people are one thing or another based on a fixed set of characteristics) is fatally flawed.
Where have you got this definition from, could you expand?
