It is just me, or do the majority of people who accuse others of being a "narcissist", or having "red flags" tend to be pretty negative people?

Bitter, unsuccessful, mentally ill and so on.

I've never known a positive, successful person who wishes for those around them to succeed to also tell me about how this and that person is a "narcissist" or had so and so "red flag". Instead, they wish to bring out the good in people. Which in extension allows them to bring out the good in themselves.

Whilst with the "narcissist/red flag" labellers, on the other hand - they seem to just have this negative outlook about themselves and everyone else. One where even the good things become a negative, and everything in their life is sucked down into destruction and negativity - and it's everyone else's fault. It isn't, these other people are positive and succeeding, which is where the "narcissist" label comes in, for them to deny reality, creating this destructive cycle for themselves.
