I don't really share that point. If the message is correct, why would the other things matter? Due to "social norms"? It is a similar problem with Code of Conducts. In general I don't care about CoCs. That does not mean I act in the opposite manner either - I just don't feel the need for CoCs.

> why would the other things matter

Because on the other end of the argument is an audience of human beings, not a theorem solver. Pretending that delivery does NOT matter, or even shouldn't matter, is out of touch with reality.
