I agree but I think it has to do with credibility and authoritative sources that used to be credible within some reason no longer being so.
I remember watching one of those movies like Zeitgeist 15 years ago (but it was about physics) and being enthralled by it and eagerly shared everything I learned with a bunch of people for months.
I eventually learned like 80%+ of that movie was made up BS, purposefully made to look more credible than it actually was.
That ruined the entire thing for me. It wasn't ethical or right to pick and choose pieces from a dishonest source -- The whole thing was thrown out much like not credible witnesses in a court case.
Again, I totally agree with the consequences of this and that it's not a good thing but if you met someone who talked about the flat earth nonstop and then told you about global warming, would you listen with the same openness if they believed the earth was round?
