When it comes to posting on watch forums, pretentious snobbery is going to be all around you; and far worse than you actually imagine it being. Yet, that is absolutely nothing compared to the sheer insanity of fans of various brands. Criticize a brand for a well-known, re-occurring issue; and expect to get sheer hatred in typed letter form directed at you. Expect to get stalked over the internet by these individuals.
I've been into watches for quite sometime now, and have become fairly knowledgeable about certain brands. When you encounter that type of irrational fan-boy, don't even bother responding to them. They're worse than trolls. At least trolls know they're doing it out of "fun," and don't really mean it. They know they're being ridiculous. The fan-boys though, they're completely serious! What makes otherwise rational adults behave this way? No clue! I have a few favorite watch brands myself. I don't bow down at their alter . . . er . . . logo? Perhaps that's the right word? Thankfully, these are just watch brands; and not human cult leaders. Otherwise, there'd be some serious problems.
Best advice: Completely ignore them. Use the Ignore List feature that pretty much all forums have. You will NOT be able to carry on a rational discussion with them, even if you were smarter than Einstein and had the patience of Gandhi.
