As with sibling comment, it's my first time reading this, it's a great read, and author really managed to write down into words some things I have vaguely thought about before.

One thing I notice, which may be the worst part of it, although I realize it might be bit too pessimistic: It doesn't matter whether A identifies with X — if B thinks A identifies with X, the discussion still breaks down and it becomes difficult to have a fruitful argument. In other words, one party can shut down and degenerate a discussion for both (or many).

It makes me think once again about the adage: Communication is a two-way street; can't have communication otherwise.

Applying the principles of keeping your identity small also makes you more open to ideas from other people.

This kind of self-reflection about identity is also very important for your own internal communication with yourself.
