>>In my observation these fact checking organisations usually fall down on the left's side of things, so either it's predominantly the right that lies, or the fact checkers conveniently ignore controversies that are open and shut bad behaviour on the left, or my perception is incorrect.

As the saying goes, truth has a liberal bias. :)
