The idiocy of a demonstration is directly proportional to the ratio of puppets to participants.
Complete idiocy would score a 1. Partial idiocy would be in decimals as expressions of fractions.
Republican demonstrations score 0, because we do not use puppets. Large demonstrations with a few puppets would score in the .002 to .1 range.
Once you get above a Marple Index of .25, there is no point in listening to anything the demonstrators have to say, because they are total idiots.
