MFK is my sanity check, this is where I ask questions, get reasonable answers and really talk with people about hobby.
In all other places, especially fb groups, I have seen is people underestimate (by a large margin) how much there is to learn in hobby if they want to and they overestimate how much they know, it's called dunning kruger effect. This is true for a lots of hobbies. Most of us are not very smart. We are trained to do certain things in certain ways that makes us do smarter things that untrained person won't. Then there are subjective things that we blindly take as we grow and think of with different ones as idiots. I believe this build up.
One more thing is, someone telling you that you are wrong is similar to physical pain. Many don't know how to handle it, one reason is many don't get into conflicts at all. Same as above, generally we grow to accepts few things and get invested in it. For example, I spent hours trying to explain my fiend that drinking water after or while eating is not bad, he just didn't agree, there is summary of research, articles online saying so. He just completely ignores them. So we grow up to not learning to change when we are wrong as we never get opportunity to.
