Everyone has their breaking point about something. Generally speaking, mine isn't yours, and yours isn't the next guy's. Sometimes the breaking point is reached with a drip/drip/drip till finally there's the straw that breaks the camel's back (sorry for the mixed metaphor, but that's all I could come up with). Sometimes it's something that pushes on some emotional trigger which hadn't previously been pushed. Since we're not at the end of stuff being revealed, it's entirely possible that a lot more will wake up one way or another about something, and one thing may be all it takes for the spell to be broken.

On the other hand, I know a very intelligent and previously sensible guy who made a post on Facebook that he trusted his county commissioners to make decisions about wearing masks (which they and he are all for), but then a few days later he posted an item about Ron DeSantis being overruled by a Florida judge regarding masks, and the guy's comment about it is that he thinks government should stay out of the debate about masks. He's got a serious hypocrisy and/or cognitive dissonance problem (known him for 35 years and never saw any of this before the virus mess). Unfortunately there's a lot of that.
