There are definitely too many of them, and I can only say I'm sorry I spent too much time trying to explain some things to them - and in the end I turned out to be some kind of criminal just trying to trick people and launder money through Bitcoin. While I wouldn’t agree that it’s just brainwashing, some people are just less intelligent (not to say stupid) to figure out some things.
For instance a lot of people believed Faketoshi but when explanations came out by experts, many of them were convinced he is a scammer.
Some realized after a long time, but the problem is that they believed in something at all that did not have any solid facts, and it was based on the words of a person who simply said "I am Satoshi". If someone who was one of Satoshi's closest associates can be convinced of such lies, then what to expect from the average person who watches it all from a great distance.
