My point, which I may have failed to make clear, is that Jim's statements are pointless.
There are ONE POINT TWO MILLION Brits living and working in Europe
This sentence does not mention mainland Europe and neither do the other "facts" I quoted. As such the figures must be taken as inclusive of persons living in Britain. This makes the "fact" pointless in advancing Jim's arguments.

As Jim went on to say that it is hard to get responses on these facts, it would help if the meaning of the facts was made clear. It might just be that he uses 'Europe' to mean 'all of Europe except the UK' but that changes the meaning of his words.

If the facts are presented clearly and unambiguously then they can be either argued with, or accepted. But while they are ambiguous it is pointless trying to refute them.
