Obviously, you are on an island although I doubt you read much. Here in Canada we vote for our MPs and if any of them happen to be of Irish, Scottish, Welsh, Italian, French, Ukrainian, Somalian, Hindu, Jewish, or even, Russian heritage and so on that is JUST FINE. We do our best to elect reasonable, intelligent, hard-working and honest people to the House of Commons and they, in turn, reflect the views and concerns of their constituents while making the decisions they are elected to, based on their own judgements. That works. I know it's different in 'Mother Russia' but no one in the world wants to go to live there, and many of those born there seem to prefer coming to places like the good old USA or Canada, I wonder why.
