>"Tiktok is like meth", would you advocate for moderation of meth?
This is an absurd statement. If someone is trying to talk about the middle cases, redirecting the conversation to the edge in order to dismiss their general comment is not appropriate.
'Edge cases exist' is not a lesson most people here need to hear.
I'm not even sure it's demonstrable that all things are good in moderation. There is a very large class of things that simply aren't good in moderation.
This leaves it generously a thought teminating cliche devoid of meaning, certainly nothing you should be making decisions off.
