Stupid Protesting Pooheads

Dear Protesters:

I understand that you are passionate and determined, but ...
NO ONE IS ON YOUR SIDE WHEN YOU BLOCK A MAJOR INTERSECTION AT RUSH HOUR.

Sincerely,
Someone who had to get a long way before my bus transfer ran out

P.S. If the object of your protest is something with obscure initials, it is generally advisable to advertise what they stand for so the people annoyed at you will at least know why their lives have been disrupted.
