The effects of certain activities eg accupuncture can be debated as there is a clear understanding of what accupuncture is, and we could look at evidence. While we didn't totally agree, we could have a somewhat reasoned debate.

If you want to debate the existance of chi, while it is not on topic, some solid proposals of definitions need to be put forward.

I don't think even the IMA forum has a definition for chi, it certainly isn't a sticky, so it might be difficult!
