On occasion, they might try to create a pseudo-intellectual air, though their arguments tend to verge on the conspiratorial.
Things like trying to associate something with "deviants" someone couldn't possibly understand, with high levels of paranoia, and outright ignoring the obvious negative implications of their actions (and sometimes trying to spin this as a "good thing" to try to take the bad taste out of someone's mouth).
Vague, tangential, and unbounded speculation with language like "maybe" and "possibly" becomes a "gold standard". Any evidence (no matter how solid it is) to the contrary might as well not exist.
There are many reasons why it's hard to take anything they say seriously.
