Lack of Tolerance

I have noticed yet again that how intolerant people we are turning into. The intolerance is seen everywhere, including the cyberspace. I have recently started visiting the Islamabad blog on 'Metblogs' and couple of times i leave my comments there as well. While putting my own comments there, i read what others have written. And i have come across 'flaming'. One person writes one view point. The other ones who disagree to that either use foul language to describe their views or try to impose their thoughts on others. No two people are the same, so how can the point of views be identical? Why can't we be more tolerant towards others' point of views? Nobody is asking us to start following those, but at least we can give others some breathing space. Now can't we?
