I have noticed that gullibility is a major factor with Trump followers, which plays into their bigotry in a big way.

As an example of how Trump (and his nefarious cabal of con men and crooks) use the gullibility of his followers is in the parable of Bannon, Kolfage, and the Great Wall Con.

Believing the constant stream of Trump lies and gaslighting is another yooge example.

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
