Shouting at people and accusing people of misinformation etc. As though you are the authority.
I hope I don’t shout. I try to constrain myself to where clear misinformation has been posted and correct it (usually but not always with sources - as you point out I am not the authority, however sometimes when it’s been several times on a thread or it’s a very common one I dispense with it.) I’m always happy to be challenged on the stats I quote, and I have admitted when I’ve made mistakes or someone has presented more complete or up to date data.
I also try to be even handed and point out misinformation from both sides (such as on some threads today when people were overstating the numbers in ICU or dead, including children.
I allowed myself to get dragged into this thread, which I regret.
As you say, it’s an open and influential forum. Many people read it, which is why I feel particularly passionately that misinformation should not be allowed to stand I corrected - because people might believe it otherwise.
I do believe most but not all is innocent - bad media reporting, misunderstanding second hand information, believing someone with somewhat more malign intent.
I will attempt to do better at being completely factual.
(I will continue to challenge antisemitism and Holocaust minimisation though.)
