There's also considerable snobbery in favor of the US-made Fenders, and many members seem to think that anything made in Mexico or overseas is not worthy. Squiers are beloved by some, considered dog-doo by others.
Whereas the criticism often leveled at Gibson here is generally done "with love" by people who play the same gear they critique.
IMO, it's more a matter of replies to "my MIM Fender, Squier, SX, etc... is just as good as an MIA Fender", than it is actual MIA snobbery... In fact, I don't think I've ever seen any of the MIA fans call the other stuff garbage - but I've seen PLENTY of questionable claims by the fans of the lower end stuff you mentioned...
Sorry if you don't see it that way - we'll have to agree to disagree on the matter...
