Arrow's work should not be interpreted in such a narrow sense. To begin with, the words used here are prolix - democracy, forum, etc. etc. Who knows what they mean! I have a (first) question to all who freely quote from Arrow (and pretend to understand his dissertation - I know I don't) - Are "majority rule" and "democracy" one and the same? If yes, I think that is a narrow definition of both "majority rule" and "democracy". If no, then people should refrain from trivializing Arrow's work.
