It can be very difficult to separate what you think from your identity - but it’s of great importance to do so. If you believe in something, then you should be willing to accept criticism work out the knots in a rational way.
You might keep your old beliefs and form a more logical way of approaching an old concept, or you might change your mind. Either way, you’ll be better for it. You’ll understand what you stand for rather than being a follower to something which truly could be wrong.
This is a problem that’s everywhere. People refuse to look at the way they were raised in a logical manner. They take offense at reasonable criticism. I see it, and I still do it sometimes. It’s difficult not to.
To be rational and honest with oneself is to be authentic.
Never questioning what you believe and still fighting for it is pigheaded, whether it’s right or wrong.
What and who are we beyond our ideas and beliefs? The fear of changing your mind is linked to the fear of dying, as I see it. Each moment bits of us fade away, never again to grace the earth. Conservatism is the only way to save them; ideas live and die as well. Why should we relinquish them so easily? Doesn’t a diversity of thought contribute to the grand beauty of life and civilization?
I am playing devil’s advocate though. Inorder for us to divine any truth we must make our judgements on logic alone.
