I don’t really see it that way. Both are premised on magical thinking without proof, via sensory misinterpretation, resulting in unfounded conjecture and illogical leaps, conspiracy, and ultimately cult following. Both can be disproven given sufficient information, but one is obviously orders of magnitude easier to disapprove.

Both are ‘too fun to give up subcultures’ and can result in and from the same paranoid delusional base.
