Is it time to start calling out bad cyclists?

Noddergeddon 07.30 this day.
I stop at the left rear of a bus which has in turn stopped at a red light. The bus is angled slightly nose into the kerb and there are railings, not a safe place to go.
Small gap between me and the bus, not enough to get a bike through, right?
Behind me a crowd of fluoro nodders. Around the outside comes Mr Nod himself, yaking away on his Iphone whilst wobbling towards me. He goes straight past me, clips my bars "sorry, mate" he mumbles before half scooting himself to the point where his handlebars will not fit between bus and railing. All the while jabbering away on said phone.
I wasn't going to say anything but I was genuinly concerned for his saftey, so I call out.
"Watch it matey, if the bus moves you could get caught".
His reply: "Fk off". And back to the phone.
Lights go green and sure enough bus moves forward about 2 m, bars get caught and Mr Nod is lucky not to get squished. Mr Nod heaves bike up and hooks bars over railing allowing bus to move off.
I pedal past and give the obvious "I told you so".
His reply? "fk off" and he is back to his phone as if nothing has happened.
If Darwin was right why does this guy even exist?
