well put.
I think of it similarly - the extremes of right and left are totalitarianism.
Unfortunately, restrictive immigration policies have been tarred with the extremist brush, and thus Europe is in its pickle. Enoch Powell was considered a terrible influence, but he has been proven right, as events show us more every day.
Four possible outcomes in England and France come to mind: 1) Civil war, 2) Mass deportations and repatriations, 3) Compomise and eventual capitulation to the Muslims, 4) Eventual assimilation by the Muslims.
Eventual assimilation, ostensibly, is what the so-called representatives of the people have chosen as the only possible outcome, but it seems increasingly unlikely.
So a restrictionism along the lines of what Enoch Powell favored would have avoided this juncture, and the cost would have been far less than what the British will have to pay in the future. I won't talk about Le Pen, other than to say, I think those who feared him but favored immigration policy changes should have rallied to someone else, but they should not have left the issue to Le Pen. We can all run, but eventually reality catches up with us.
