Well, since it seems I have been overly liberal in my "Civil" voting, I am now limited to 3 comments in a 24 hour period -- and I can't find any guidelines for what is "civil" so as to comply. So, this is probably my last on this subject.  

Australia I couldn't speak to.  I know they are somewhat xenophonic particularly in regards to Asians.  Mexico?  I think their "lack of diversity" has as much to do with big Catholic families as anything else.  To my understanding they are quite willing to take in expats, retirees most so.
