While this cyclist was certainly wrong to run the red light, I personally would not generalize the behavior of one or even most cyclist to all cyclists. If a motorist is frustrated by a cyclist who rides irresponsibly, and decides to take that frustration out on me, I will blame the motorist only and not the cyclist. The same goes for motorist. If one motorist is aggressive and reckless, I will not take out my frustration with the aggressive motorist on motorist who drive responsibly. Any motorist who decides to generalize on all cyclists because of one or most bicycle riders and further decides to drive dangerously around all cyclists because of this generalization has some problmes of his/her own unrelated to the irresponsible bike rider.
