This seems to suggest that because we can't always tell facts from lies, we must never act on information as being factual. That to me just seems wrong.
> Would Twitter by OK to ban people complaining about stolen elections in some Latin American country (where we can all agree that they might very well be stolen)?
They indeed were (e.g. Maduro in Venezuela is a recent one). I hope Twitter doesn't ignore such situations. There will always be a need for biased and subjective action.
> There has been no shortage of actual stolen elections and/or election fraud worldwide (and one would presume, in the US historically).
One should be really careful when talking about election fraud, to not confuse widespread systematic outcome-changing fraud (which is extremely rare) from instances of fraud (which is almost universal in any election but usually doesn't matter).
