Is it time to start calling out bad cyclists?

i called out a twat who had only a minute earlier undertaken me on Jamaica road. Note: He had already undertaken me minutes earlier so he was already on my "watch out retard ahead" radar.

So he's in the bus lane riding primary, fine, good for him. I'm riding faster so I move to overtake on his right. As I am passing him, he starts to veer into me without looking over his shoulder or any prior indication. He comes perilously close to bumping into me so I turned to him and say:

Me: Do you mind?
Him: stupid look on his face What?
Me: You're steering right into me
Him: Because I'm turning right!
Me: I'm in the middle of overtaking you
Him: You shouldn't be overtaking me, I'm turning right at those lights over there
Me: Did you ever just maybe consider checking over your shoulder or indicating that you wish to turn right?
Him: You should have passed me on my left!
Me: Thats called undertaking, you shouldn't be doing that.
Him: You don't know anything.
Me: You're the reason my mum once told me to assume the world is full of fucking retards
Him: Fuck off you cock! You should learn the rules of the road before you cycle on them!
Me: Piss off you fucking twat!!! ROOOAAARRRR

So I lost my temper a little bit at the end.

Probably the same bellend who crashed into the back of me on Jamaica Rd yesterday snapping my rear mudguard.... Wasn't a silver mountain bike was it?
