Is it time to start calling out bad cyclists?

unfortunately i met a bad cyclist yesterday. first thing I knew about it he struggled to ride up alongside me then started unloading some abuse which ended with him calling me 'Mr. Grumpy Pumpy' I kid you not. He was upset that he nearly ran into the back of me while i was going around a bus in a perfectly normal road manouvre. He was obviously watching my back wheel instead of ahead anticipating what was coming. Then he tried to speed off and when he realised we were going to meet again at traffic lights he jumped a couple and nearly caused accidents involving cars and peds. When we did draw level further down the road he started spitting at the floor and pretending to be all nonchalant. I didn't speak to him but just gave him the eye so he told me that I should have put my hand up and said 'sorry' I told him that I had no problem with that but he needed to change the tone of his voice if he was talking to me. Then he darted off a left turning shouting 'Fuck you' . Yo often encounter this type of 'Am i the only person in the whole world who knows how to do anything properly' character behind the wheel of an automobile but if you do see him he'll be riding a dawes with paniers on the right reer and on the handlebars. Other distinguishing features would include the edginess of a man whose medication has run out. Fear not though , absolutely no trousers, 100% mouth.

Plenty of tits like this out there, notice it a lot on The Hipster Highway. Was on there yesterday and I was in a 'fuck this cycling quick' kinda mood cos of the tube strike and infux of bells on the road, I fancied a pootle so I decided to stop at every red light.
It's only then do you watch and realise the amount of helmets that RLJ and actually think it's a 'show-off/cool' kind of thing to do
There's ways and a time to RLJ but 99% of them deserve to get knocked off
