Is it time to start calling out bad cyclists?

Was sat in the ASL this morning behind a large number of cyclists, patiently waiting for the lights to turn green. Then a flurowarrior squeezes into a gap to my right that isn't wide enough, bumping into my side with his bars. It doesn't hurt, but enough for me to say "excuse me, do you mind". He looks confused, so I repeated "you just bumped into my side with your bike". He shouts "you should have moved further forward! There is space in the box!!". No apology, no nothing. What a fucking clown, I swear there is something seriously wrong with some people. I should have just kidney punched him, I am so disappointed in myself.

Exactly the same thing happened to me the other day, on CS7, long story short this guy desperately wanted to get past me into the blue box because the front car was indicating left, moaning "you're in the way, you must move forward"

a) if you're that edgy about a car indicating left, just drop back
b) there were 20 bikes at the lights, I guarantee the driver knew we were there

Without looking I knew he'd have a bell, as we all pulled away I said "ring your bell, you'll sound like even more of a cunt"

"Cock" I heard him retort a little further down the road.

I think we were both right.
