I see it as unpopular in the sense that each of us individually struggles with our own acceptance from our own interpretation of social relations. It only takes one unpopular opinion in this case for it to be true. In this way, our flaws often become the most dominant parts of who we are in a social domain, the things that we fixate on more than anything else.
I completely agree about being radically honest with yourself. But even further, we should even question why we see certain traits as flaws and others as strengths. Not to entirely devalue their categorization, but to recognize why those traits, good and bad, and their social implications are important.
That is up for personal interpretation
