Is it time to start calling out bad cyclists?

Pandering to them would be tolerating people when they start going all 'cyclists are all this and that'.

Pandering to them would be having it in for shouty camera users because you think they make you look bad.

I don't cycle too much like a twat because I'm not too much of a twat.

I agree. I don't cycle much like a twat because I'm not too much of a twat, or at least I delude myself to that effect. At the same time, I disapprove of shouty self-righteous confrontation-seeking camera-using cyclists not because they make me look bad, but because they reinforce the stereotypes which the stupid and the ignorant hold so dear. Putting people in stereotypical pigeon holes based on prejudice and bigotry is stupid, but you don't solve that by reinforcing those stereotypes.
