Art of criticism

I wonder if this is a societal defect but I find most of us being very sensitive to criticism ; be it in any context- individual ,community ,state or nation. Even if accidentally or indirectly someone points our flaws or something they don't approve of, we defend in a second without assessing even tad bit if it may or may not be right in any way. But why is it such a big deal. What if we have flaws? What if someone doesn't approve of our opinions /actions ? We could ponder and correct ourselves if needed and move on. Why this erratic need to defend ourselves all the time? Not just that, even if it is a government we support politically or a particular Khan in Bollywood we love ,we tend to blindly support and jump on every other person who gets critical. 

Although I do agree it's not always about whom criticism is targeted at and how it is accepted, it's also about how someone criticizes. Most times it reduces to an argument winning competition which in turn results in words which don't serve the purpose. Also if the person criticising thinks too much of himself , then no one is going to care for his/her criticism. On the other hand if it is someone who has accepted their flaws and is comfortable in their own skin, they don't even let u feel they were being critical. Now that is exactly the reason why I feel that the act of being critical or criticized is an important art for any kind of intellectual brainstorming.

For something like a community or religion we should realize and accept that if there is no one to point us when we are wrong ,then we will stagnate and anything which is stagnant becomes obsolete with time. Change is inevitable and natural evolution of a society is what is going to keep it healthy.That too in a society like ours where there are too many forces pulling us in different directions, pluralism should be celebrated. It is very important to have a conducive environment so that our democracy flourishes. I earnestly wish that we would all learn to respectfully agree to disagree and realize that the whole beauty of democracy is to have the right to dissent and still peacefully co exist.
