Did you just lump me in with the "people who are shouting "troll""? I believe I said the same thing as you in so many fewer words. If the preacher (poster) reveals doubts (negative bitcoin comments) then the choir (pro-bitcoin forum members) will be shocked.

There is a difference between someone posting technical/fundamental reasons for declining price in the speculation forum or someone posting cryptographic/networking concerns in the development forums versus a tiny minority who contribute nothing constructive seeking only a reaction. I believe unconstructive posters are trolls by definition, it's only that a bitcoin forum has a higher tolerance for blind love for bitcoin than for blind hate.

For example, I've been involved in numerous discussions where people legitimately don't understand massive numbers or exponentiation (a common human defect) and while the posters are very wrong (such as fear of accidental address collision), the responses tend to be thoughtful, patient, and ultimately productive if not redundant. I've generally found the "troll" label rare and appropriately attributed, on the other hand I don't read the majority of threads after reading the title.
