I agree! Most good people are nice, it is complemntary after all.

At the same time, without getting trite, being nice does not make people automatically good, and is often a performance to get away with vile shit.

To paraphrase another idiom, people who are easily offended should be offended more often. People often dismiss others because they are not “nice” AKA not submissive or servile to their opinions or demands. Oh, this person is “mean” so I get to talk shit about them or ignore them.

Yeah, not every good person is a good role model, one can always act better than the people they admire.
