The root problem is segregating the world into buckets like that.

Whether its being used in the condescending version or the self-deprecating version is beside the point. When you go into social situations sizing people up as “normie” or not the preconceived ideas about the other people become an obstacle for communication.

I don't think GP does either, other than 'self-perjorative'. At least that's how I see it - a sort of semi-self-deprecating acknowledgement that the speaker is not 'a normie' (whatever that means, really).
