I don't understand this point. I'm saying that whether or not a particular subject is a "crank" one is not closely related to either its truth value or whether that truth value is even ascertainable.

I haven't made an argument for why the ones I've listed are actually crank subjects; I consider those granted and I'm not particularly interested in justifying them.

The things you listed form a cluster of beliefs that gullible, uneducated, and often toxic people flock to, and that makes those positions quite unattractive even ignoring their respective merits, which are not great.

What I take issue with is the lack of symmetry. For every COVID denialist, you have a zero-COVID enthusiast. For every election denialist, you have an impending climate catastrophe doommonger. For every great reset conspiracy theorist, you have someone who believes we live in a meritocracy. Each of the latter positions is as merituous as their counterpart, but the former are treated with a disproportionate contempt.

I think symmetry in this case would amount to false balance. Why even bother to frame things this way? It's self evident to most people that crank views run the gamut of social and political backgrounds; like all things in life, we prioritize our discussion of them by their perceived impact(s) on our lives. COVID denialism has more of an impact on my life than an anti-nuclear crank does.
