Don't worry, Dordie and the member concerned have a "personal issue" going on that's been rumbling on for years. It erupts in threads sometimes but you shouldn't have any problems with either of them.
Some of the discussions and debates on here are "serious", others are less so. Same with the members, some prefer serious, some prefer fun. It takes all sorts, but we try and cater to everyone as far as possible.
Some people's opinions are very forthright and there are no punches pulled, that can take a bit of getting used to, but it certainly makes for interesting discussions.
