Is it time to start calling out bad cyclists?

so mike your saying you dont give a shit unless it affects you? nice to see your concerned with the safety of other road users and not just your own.

I used to if it endangered me directly. Now I just shake my head and give them a wry smile.
If they do something very dangerous that almost results in an accident to me then I will give them a quick mouthful and be on my way. Also, if they do something very dangerous towards anotehr cyclist then, if I catch up with the, I will politely say, your driving skills are not great

No, if you had read this bit then you would not have been able to come to that conclusion. I am saying I don't have time to take the world on my shoulders and am merely wondering, where does one draw the line?
