Is it time to start calling out bad cyclists?

Obviously can't know the circumstances but I have had a few problems with peds recently on shared paths and even the road and when I've raised the issues I've found it them that over-react. I had a chap standing in the middle of a (quiet) one-way street, on his mobile phone and looking upwards towards presumably who he was in conversation with. I pick a line around him only for him to move backwards, so I adjust the line only for him to turn and see me and do the worst fucking thing possible: stop dead in my path. I brake and swerve and throw a hand up and say 'this is a road mate' only to get a volley of grief as I roll away. I've also had peds eyeball me, eyes meeting as I swoop down and for them to simply step out in front of me anyway.

Sorry bad peds thread >>>>>>>
