What is society if we just accept all problems as part of the person or else society will be toxic?
Also has there ever been a society where flaws are just accepted without any kind of judgement? I would suggest that in those societies they simply did not classify them as flaws.
> If we all just accept that everyone has flaws and we can express them, then we can take them into account and deal with them
We can and do accept that but again that doesn't fix the flaw or absolve the person of the responsibility of the flaw.
I personally think the toxicity of modern society actually arises from the fact that we don't feel comfortable openly judging people's flaws, rather than the opposite.
