While I certainly won't condone this, I also think it's a different class of problem from blatantly running a red light that has been red for a long time. Lights are timed to tolerate some abuse when it comes to trying to squeak through.

What I see bicycles do on a regular basis (and what this one particular jerk did the other day that really stuck out at me) is proceed through red lights that have been red for a long time. On a good day, they do it after stopping and waiting for a while. On a decent day, they check for traffic and only run the light if there's a hole. On a bad day, they just blow through.

I object for two reasons. First, even though they're likely to take the physical damage in a crash, they're still imposing potential emotional damage on others. Even if they're not at all at fault, a normal human will feel awful for hurting or killing a bicyclist while driving. Second, it gives all bicyclists a bad reputation, and that harms me when I'm on my bicycle.
