OK. Thank you for pointing that out to me.
Maybe to clarify . . . my OP complaint was against those who make disparaging comments against large groups of people of whom they have no personal knowledge.
Such complaints are false on their face, being overgeneralizations. Such comments are presumptuous, given comment on things the speaker is ignorant about. Being false and presumptuous, they are therefore fleshy and unedifying. Being fleshy, they serve the speaker.
So the one who says such things is, as I see it, making disparaging comments about others so serve some personal need, generally speaking, I think, an emotional disorder.
In the simplest terms, people tend to put others down to make themself feel better about themselves.
Someone who feels the need to be superior to others will include that in their words, making sure everyone knows how much better they are, in whatever sense they need to address there inner emotional lack.
Anyway, in my research, and interactions with people, this is what I see, what I think, for what it's worth.
Much love!
