I've spoken about the nastiness of criticism or being critical. Forget the unpleasantness, the idea of making someone feel bad about themselves or their work/art etc. is bad. We have no right to make one of God's children feel bad about themselves. So reason yes, but never criticise.
That is one of the reasons why I don't want to criticise SRK (or anyone else) anymore. That is the reason why I would rather review a film/book/album that critique it.
And here is what "Sacred Space", TOI's pride has to say about Criticism. (Substitute Churchill's use of "criticism" with feedback. He was a politician, not a corporate citizen)
Flatter me, and I may not believe you. Criticise me, and I may not like you. Ignore me, and I may not forgive you. Encourage me, and I will not forget you. Love me and I may be forced to love you.
~William A Ward
I have no right, by anything I do or say, to demean a human being in his own eyes. What matters is not what I think of him; it is what he thinks of himself. To undermine a man's self-respect is a sin.
~Antoine de Saint-Exupery
Criticism may not be agreeable, but it is necessary. It fulfils the same function as pain in the human body. It calls attention to an unhealthy state of things.
Any fool can criticise, condemn, and complain but it takes character and self-control to be understanding and forgiving.
Three-quarters of the miseries and misunderstandings in the world would finish if people were to put on the shoes of their adversaries and understood their points of view.
~M K Gandhi
I hope to emulate what one of my idols preached.
