So I'd certainly say Reddit is at least comparable. Additionally, I see fact checks on tons of conservative posts on Facebook and Twitter (rightfully so most of the time). But the same procedure isn't followed for liberal posts.
I haven't seen any possible misinformation warnings on Facebook or Twitter for something like: people claiming the BLEXIT supporters at Trump's recent speech were paid. According to ABC News, some supporters travel and room/board were paid (but they didn't release any of the emails, just allegedly quoted them). So it would be misleading to say that BLEXIT supporters were paid to attend the speech, it should be labeled as a "possibly misleading" statement like the claims from the right typically are. I mean, the emails haven't even been released and/or verified as existing and people are just running with it because it's ABC?
Edit: would love to know why I'm getting downvotes for providing a comment with a source and a different viewpoint?
