You don't have to be involved with fly fishing very long before you discover that fly fishers are, for the most part, quite opinionate people. This has been so since the earliest days of the sport. Read any of the early fly fishing books and it will quickly become evident that fly fishers have been debating various aspects of fly fishing since its earliest days. Unfortunately, it also became evident that the opinions could quickly become a source of disagreement and some of them even reached the stage of name calling.
