We all think we see the world objectively, as it is. If others don't agree we think that either they have not been exposed to the relevant facts or else they are blinded by their belief or philosophy. In other words, "everyone else is prejudiced, except me, I see things as they are". That view then allows some to point the finger.

It's a pain dealing with other people's judgements and prejudices and only the most noble or patient can be unaffected. But fingerpointers have to live with themselves all the time - that's their own punishment!
