That depends BTNG. If people want to tell others to get a life, or a sense of humour, or suck it up, or trade whatever insults they deem necessary, they forfeit the right to be taken seriously in a logical discussion. I'm happy to visit rough pubs and friendly locals and adjust my behaviour accordingly. Ditto message boards. There's no point coming on like Wittgenstein in the Sluggers Arms or Johnny Mental at the Ritz. Consistency is the key.
