Few people on here who look down on others, think they are thick, stupid, less educated and so on. Not experienced this with GB but with some others I have, it's horrible.
Sorry to hear that. I hope you don't include me in that group.
My take is the opposite, though. There are a couple of annoying pedants, both decent lads, but one occasionally so relentless I have had to put him on ignore. But I don't recall ever being talked down to. And almost everyone is reasonable and will engage in a conversation. The other 15 I have on ignore.
Meanwhile there are some people only too ready to waft an ill-founded whimsy into a serious conversation as if it is fact or at very least just as valid as anything anyone else has said. Sometimes it is just nonsense and if so it should be called out. I suspect that some of the people who post opinion in this way may get shirty if rebuked. Well, to paraphrase an ex neighbour's ten year old kid when her mother complained the ferret had bitten her, they should 'be more ****ing careful' with what they post; tough luck.
Nevertheless I have apologised on numerous occasions for getting things wrong. If you're wrong, you're wrong. It isn't a competition.
