I am not sure why your comment is flagged. Anyone familiar with the history of postwar Europe will recognise some important points that you mention. Others might disagree with your opinion, but I feel it deserves to be read and discussed. It certainly should not disappear.
Czech Republic has around 100k vietnamese and about 500k ukrainians which for a pop of 10m is significant numbers. Both of these nationalities have different cultural background and values and yet there's no problem with respecting rule of law and natural order in the country. Live and let live.
