Meh, it's the same as any other fanbase. You've got your die hards and your bandwagon fans.
I'm happy you had a good experience, but most fans from other teams tend not to have such a positive experience. The bandwagon fans are the loudest , and everyone tends to judge "us" (if you can refer to an entire fanbase as an individual being) as loud, rude and obnoxious (oh, did I mention arrogant?).
