First of all, your "personality" is comprised of over 170 recognizeable different traits if not more.

Everyone has very different aspects to their personality that change depending on your mood, genetics, environment and various other factors.

Even the most comprehensive test for supposedly identifying overlapping and consistent personality characteristics like myers-briggs, still have various flaws in their analytical methodology and are deemed unreliable for a number of reasons.

Given the fact that personality encompasses so many different traits, is highly nuanced and subject to change, it's very dumb and brash to pass judgements on people by labeling their personality as good or bad as if you are the moral arbitor.

I've noticed this is a common trend among lowbrow people who like to label others as having a "bad" personality. (all while thinking their personality is top notch, amazing and one of a kind)
