It's absurd to call capitalism the problem for e.g. pollution (which is a typical example of 'capitalism is the problem' statements), which every economic system faced (and the communist systems handled much worse than the capitalist), not to mention comparing slavery to 21st century employment in the West. The people uttering those statements know that, they're neither stupid nor children who haven't yet gotten an education, so they're lying, and they're doing so to manipulate.
A similar absurd lie that is intended to manipulate: Russia is being attacked by NATO and only defends itself against the fascists in Ukraine.
> It's self evident that there should be separate standards for that.
Sure, but they shouldn't be based on whether something is true or wrong, absurd or plausible, or said with intent to manipulate or inform.
Better criteria are required, or we'll be back to Twitter's stance of "this instance is against TOS, and that same thing isn't, because we feel like the author didn't mean it the same way", which comes down to "there are no rules other than don't do something/be someone I dislike".
