Actually, upon further reflection, there’s almost an addiction like component from the behavior of the right:

- First, come up with a bunch of crazy sounding but not totally implausible conspiracy theories to get people’s attention

- After awhile, as these theories become the norm, they don’t draw attention anymore.

- So then you come up with even crazier and more insane theories to draw attention again.

- Eventually those theories become the norm and people get tired of them.

- Lather, rinse repeat

It’s just like always needing a stronger hit to get the high.
