I'm not reversing my position at all. I am arguing that some topics can be discussed with context-free universally true premises and some cannot. Nothing I have said is inconsistent with that.
> This is not a prerequisite of all discussions.
is equivalent to:
Some discussions do not have this as a prerequisite.
You're literally reversing your position here:
> Are you suggesting that some topics can only be discussed if
We were not talking about all discussions, we were talking about how some topics don't play nice with this method of having a discussion.
> This is easy to discover and correct for if both parties approach the discussion without being disingenuous.
You mean like not pretending you were talking about the opposite thing you were actually talking about one comment ago?
