I don't like traffic. They should all just stop and take a chill pill, have a nice cream soda or something.

Seriously, IMHO non-violent demonstrations have value beyond the actual message and that overrides the temporary inconvenience. Sure, too much of anything is bad for you, but in general the right to assemble and voice an opinion ought to be protected. Even if it's an ignorant, biased, or simply retarded opinion. Anyone who disagrees is free to counter-demonstrate, although it seems to me that the morons are often better organized and able to raise a rabble of similiarly ignorant but bored or lonely people willing to gather for almost any reason.
I like the solution I saw on tv... Go to these rallies and get them to sign petitions to ban dihydrogen monoxide (water), since it's clear that the govt has covered up the fact that every cancer victim in history was literally saturated with dihydrogen monoxide from birth, yet the govt does nothing about this!
