Group sourced refrences, summarized by often biased volunteers, are not 'facts'.
Wikipedia, in a random sampling of information, came in as equally or more reliable than nearly any other privately published reference. It's not perfect but it doesn't have to be.
Often biased volunteers? refrences? Okay, chief.
They present their INTERPRETATION of the facts. For example some may call ANTIFA as a force for good and others as a terrorist organization. Snopes themselves have a pretty clear slant/agenda.
