Your definition of "common sense" is strange. You use commonsense and go straight into an elaborate concept.

Also your statement of failure of section 8 is without substance or source.

> I see no evidence that this was the case.

You also don't provide evidence at all on either side.

You present your side of argument without any evidence and went on opinion. No sources.
