Would you blow those red lights if you were in a car? if the answer is no then you should not do it on your bike.
I hear about it a work all the time since my office is right on a busy bike trail. We witness many accidents out there mos of which are because a bike rider did something stupid. The people I work with (and I do work for a bike friendly company) wonder why cyclist think they are above the law. I wonder that myself.
Bekoligist, pedestrians get hit by bikes in downtown Seattle all the time. They allow cyclist on sidewalks a very bad mix.
