@ Draco - If you take that post at face value, all it is saying that they don't agree to your proposal to "agree to disagree'. It is not necessarily a "bait" post, nor is it disruptive or rule breaking. The discussion has continued on quite a ways past that post, and there is no need for moderator action at this time.
If you still see it as a "bait" post, then it's best to continue to ignore it.
