Is it time to start calling out bad cyclists?

More general question - why does someone have to know you in order to have an opinion (albeit a negative one) on your behaviour? Given that we're all judging each other all the time, is it voicing the opinion that's the issue, or should we all try harder to ignore the behaviour of people we don't know?

Kind of makes me think about the shouty folk on Jeremy Kyle shouting "You don't know me, so don't judge me!"

I don't need to know you to think you're a fool, love.

Do we all really have the time to have a go at people for minor infringements.

Shall I shout at the people I see dropping cigarettes on the floor?
Shall I shout at people in the parks whose dogs are not on leads in the green area?
Shall I shout at people who push in at bus stops or at the bar?
