The "real world" includes such people as journalists on newsrags, political activists for extreme parties, proselitising members of fundamentalist sects, racist and sexist bigots, and the president of a supposedly civilised nation.
If you have never met, heard, seen or read any of these, then you must be sealed in a soundproof windowless room with no access to media.
If you have come across them, and believed them - well, I'd say you are too intelligent to be taken in, so that isn't relevant.
If you have come across them, and recognised their illogical hatreds, then why single out a minority of Gransnet posters to prove that is a unique sink of viciousness which you must ostentatiously reject before it sullies your own views?
