I read OP's post as a change from an absolutism to pragmatism. Absolutists on any matter are at risk of behaving like paladins* or tyrants. The change I imagined from it was from "Any speech is good regardless of consequences." to "Yeah, sometimes there are better (such as, less hurtful, or more productive) ways speak, and encouraging that is sometimes helpful."

* A paladin attitude: "Anything which supports my view is Right; any fallout from trying to enforce my view is Good; anything that doesn't support my view is Wrong; anyone who is against my view is my rightful enemy upon whom any harm is Righteous."
