Is it time to start calling out bad cyclists?

Had a run in with a fool on a fold up bike this morning on Westminster bridge. Suit on , briefcase strapped to his back . you know the type . He was in the middle of the road cycling up from the lights by the hospital and I was behind him in the cycle lane. He was going quite slow so I was catching him up on the inside . Then a car beeped at him so he started wobbling his way into the cycle lane towards me. He only looked when he nearly collided with me. I didn't say anything as I don't call people out , as you know. But the cheeky cunt started shouting at me , saying to look where I was going. So I threatened to throw him off the bridge. He soon shut up. And I went to work as normal.

So you saw exactly what was about to happen but just carried on anyway ensuring some kind of conflict would occur. Nice one. There is a difference between letting someone know you are there and calling them out.
