Your own link says that nearly half of all Americans and 70% of Republicans think fact-checking is biased. That's the attitude I was referencing when I said that fact-checking is "widely heckled". If half of an audience boos you, that's a lot of booing.

I have no idea what you're arguing. Your own link says what I said.

I'm not saying anything about the fact-checking itself. I'm not on Twitter or Facebook. I haven't seen any fact-check posts. I'm sure they try their best to be accurate. I prefer to get my information about the most hoax-prone topics from authoritative sources - primary sources, news agencies, newspapers of record - the more boring, the better.
