Hi:

I recently received a comment from someone that given |X| > 0 and |Y|
0, X x Y can be empty.

Please provide a link to the original comment.

I'm afraid you have something of a track-record for misunderstanding
comments.

So true. Let me gather my thoughts and then I'll post the proof in
another thread. Then you can comment on why the other recepient states
X x Y = 0.

Actually he didn't ask you to gather your thoughts - the request
was that you show us _exactly_ what the comment said. Word for
word.

The point being that what you _say_ he said is obviously false.
But there are various _true_ statements that might sound a lot
like the false statment that you claimed was said. So it could
be that while the statement you posted is false, the _actual_
comment you saw was actually true.

One would think you'd want to find out whether that was what
happened. But if we're going to find that out then having
you gather your thoughts is no help - we need to see
_exactly_ what the comment said.
