Is it time to start calling out bad cyclists?

I don't normally engage other cyclists, but so much stupid riding was going on on the way home last night and on the way in this morning that I just had to. Won't be doing that again. Cyclists are tossers Aggressive, arrogant tossers who are beyond help. Undertake, filter dangerously and overtake signalling cars all you want, I'm sure you'll learn your lessons eventually.

this seems to be the latest fad on CS7.
