zero tolerance

Should we judge others as we judge ourselves? Should we apply the same strict and rigorous standards to other people's behaviour as we apply to our own? The current craze for 'tolerance' seems to say not: judging others is Out Of Bounds. We should be Tolerant.
One can see where it came from - and I think it came from noble motives.
1. Judging without knowing the whole story should be avoided.
2. Condemning someone for ever, just because they have slipped up once, is unfair.
3. We should try to understand the reasons for people's behaviour rather than taking the actions out of context.
4. People are only human.
But these are red herrings: they only say we should be cautious, and understanding. In the same way that we should when we judge our own behaviour. And they say that we should not make blanket condemnations which cannot be reversed if the behaviour or the attitude to the behaviour changes at a later date.
What do we do with our own behaviour, and how would we wish that others responded to our 'slip-ups'? I think I would wish that people judge my bad behaviour harshly, at least until I recognise it myself - and come to regret it. Then I would wish them to be understanding. How can we come to know our behaviour is 'bad' if people are only ever understanding and tolerant towards it? I don't want people to tolerate my bad behaviour.
And why on earth are we bothering to teach people what is 'right' and what is 'wrong' if we don't want them to apply these terms to anyone (except themselves)? What happens if - perchance - that sacred cow International Law happens not to have got it quite right what is 'Right'... but no-one dares to make a judgement outside its boundaries? How, after all, does human rights law develop if not by people making moral Judgements outside what is written now in international law - and pushing to bring it inside? Yet making moral judgements is seen to be no part of human-rights-education (so-called).
The power of human rights is not in what is written down in international law: it is in its inherent moral force. If Human Rights Education is to have any meaning and purpose - surely we need to be teaching people how to make sound moral judgements, and act on them. Tolerance of this unequal and inhumane world-system is precisely what is keeping it going.
