I believe the word is “gullible.”
Some people believe the “truth” is anything they can get away with.
Along with that; I heard something on of all things a Star Trek TNG or Deep Space Nine episode, I can’t remember. It was stated by none other than Whoopi Goldberg:
“Truth is in the eye of the beholder”
Now that had to come from Progressive lefty Roddenberry as it is the virtual template phrase for the ultra left wing psycho cabal. No right or wrong, no good or evil, no truth no moral absolutes period, only what the group thinks and “feels” at that particular moment in time.
