I speak as the descendant of "immigrants" French Hugenots (17thC) and more recently German, Italian, Spanish, Welsh, French ... my ancestors all came here because they perceived life to be better here .. and integrated into it.

That's because CarolC you live in a very "young" country. When one can trace genetic/cultural roots back to Neolithic times and earlier and stand in a literal and cultural landscape inhabited and shaped by one's direct ancestors (Witness the 9,000 year old skeleton found in Cheddar, Somerset and who's DNA was a match with a school teacher in the next village).. set that against a cultural immigration that has only taken place in the last 20-30 years and which in places seeks to not just dominate but replace .. educational systems, political systems, culture, philosophy, every aspect of life as it is knowm ... with, in many cases repressive, ideology that has not progressed since the Middle Ages when Islamic culture was at its zenith.
