Is it time to start calling out bad cyclists?

i have no problem with people pointing out hazards, i'd rather people were thinking about the other people around them than living inside their own little bubble and riding like there's no one else around.

considerate riding > selfish riding > oblivious riding

not sure why it annoys people so much when they're not doing anything to actively interfere with your riding.

This. There are plenty enough tossers out there who don't give a monkey's. If you point whilst swerving to avoid something, that seems fairly clear. I usually make eye contact too.

I'm always pointing out glass and bigger holes, even to drivers occasionally. Force of habit from years of marshaling.

Come to think of it, I can't recall a stranger ever doing that for me. F***ers!
