@mgorny I used to think the same. The thing is, discussing with those people is pointless, they are way too far into their imaginary world, and way too much of their self-perception is based on the belief they are smarter/better by "understanding" the topic like the general populace doesn't, to be swayed by anything less than arguments from a person they really look up to, peer pressure applied over long time, or maybe a long course where all of their points consistently get proven wrong until they finally admit to themselves they may not be right.

Furthermore, they tend to make for a loud minority, creating the illusion that things are much worse than they actually are. If they ever get bad enough to majorly influence the rest of society I'll learn about it from more sensible sources than themselves.
