“This nation was conceived in liberty and dedicated to the principle – among others – that honest men may honestly disagree; that if they all say what they think, a majority of the people will be able to distinguish truth from error; that in the competition of the marketplace of ideas, the sounder ideas will in the long run win out.”

The lists on the internet are "the marketplace of ideas" and this statement is even more true -- altho the elite do have their hands in all of it, shelling out misinformation at an alrming rate

Rick Z, YES ! I think the process goes through its ups and downs, tough to easy, etc. cycles but ultimately, accurate (maybe not the majority).

People may honestly disagree as long as they bow down to the cult of political correctness. Mustn't say anything that could possibly offend anyone.

"... the sounder ideas will in the long run win out."
Measured on what scale(s) ?

Honesty , walk upright, the armor of light !! Is the Key. Many always give into temptation. The few stay abreast !
