I've often wondered how people can justify making this statement, or similar ones, when doing so is almost always judgemental itself.
"I can't stand judgemental people"
"I don't like to judge, but I think X is wrong"
"Don't judge me, you arrogant/ignorant X"
I form judgements about people from their accent and appearance, but I do my best to overcome these judgements and assumptions.
I judge people according to the way they talk or present themselves, and I question these judgements and change them if necessary.
I judge people on the things they associate and identify with, and I question these judgements too, but I rarely need to change these.
Finally, I judge people on their actions, and I simply don't see how I could live life without doing this. I judge their actions according to their moral standards, because I dislike a hypocrite, and a weakened version of my own moral standards.
Everybody judges subconsciously. I hope that nobody will try to tell me that they honestly, hand on heart, do not form any instant assumptions about people based on first appearances.
I also believe that everybody judges consciously. What would be the point in having a moral code, if one were not able to disapprove of those who fall outside that code? Why would we bother to consider some actions good and others bad if we did not allow it to affect the way that we perceive the actor?
There is nothing wrong with judging people. There is also nothing wrong with treating people differently based on those judgements, so long as the judgement is adjusted in the presence of evidence that it was ill-formed, the difference in treatment is legal, and the difference in treatment is based on moral principles based as much on logic as it is possible to base such things.
I therefore view with the utmost scorn those who say "I hate judgemental people", since they do not recognise the hipocrisy of their claim, its judgemental nature turning them into one of the very people they profess to hate. My loathing for such people is, of course, judgemental, but I'm not claiming that I don't judge, and I would gladly listen to the argument of a person who claims not to be judgemental, and adjust my opinion of them if they can tell me why it is not the utmost hypocrisy for them to make this claim.
