That is correct - I am protecting my (very expensive) time from having to waste it on convincing you of something that you don't believe in, when the convincing would not do me any good anyway.
So, no, this is not about "convincing arguments". As with all of existence, this is about making a statement of who you really are and inspiring others. There is intrinsic value in that. I believe in leadership by example. I do not believe in leadership by "convincing arguments".
Good discussions can make you see things differently, take a new perspective that you had not fully considered before. If you only make "life statements" and never cordially exchange points of view, you lose a much useful way of changing your own; you risk keeping yourself in a warm sense of certitude, losing precious feedback from other people's insight.
