Who will fact check the fact checkers? Well, perhaps these trusted sources should implement a system similar to Quora/StackExchange but for opposing arguments?

Who will fact check the fact checkers? Well, perhaps these trusted sources should implement a system similar to Quora/StackExchange but for opposing arguments? Lots of comments call into question the biases of sites like Snopes/Politifact/etc. and allowing some sort of adversarial response would help claims about 'leftists wanting to control our minds.' Maybe it's just a widget at the bottom of a fact check post leading to a StackExchange'd subdomain. A wiki or subreddit could work as well. Anyone looking for a side project?
