Christian version: do onto others as you’d want them to do onto you
Buddhism: don’t get bad karma
Islam: None of you has faith until he loves for his brother or his neighbor what he loves for himself
(Compare and contrast with capitalism: the poor don’t work hard enough therefore should suffer from poverty)
In context of this community, I personally feel it’s intentionally-basic ground rule to keep healthy relationships with other people over the argument
I feel admins don’t want to be overly prescriptive how you “suppose to” act but in every heated/controversial discussion they will try to keep peace/civility at the expense of “the truth”
Of course, this approach has its cons but one can always stroll to the instances with fewer/no ground rules while keeping your beehome clean and friendly
I agree and what I think is specifically meant with being nice is that you should to be respectful to each other. Anything else will get us nowhere in life.
