Is it allowed? Thread splitting

For example, a sidetrack about an xkcd comic came up, and I want to start a thread about it.

Here’s what I contemplate before doing so, because I really don’t know.

Copy and paste the start of it, as well as all related responses, in a new thread. But in great debates? IMHO? Is a discussion of facts and fallacies of a web comic (which I love), where does that go?

It’s contentious, not friendly.

But it’s not a Pit thread.

It’s not a question thread, but I would love to submit it to Cecil.

Can the actual posts beMod moved into a new thread? Creating it out of whole cloth?

What would the name be?

A sample of the conversation

And that is about the simplest post on that matter.

And, most importantly, does any of it really matter?
