"We've done a lousy job of assimilation, and we're paying the price."
We've? Who's we've? You must be talking about multiculturist wankers who run our schools and who have cowed most governmental institutions and banned policies of assimilation. Otherwise, its the crappy attitude of the illegals to blame, not we, as in "we've"
Your first assertation is correct, the second is due the first.
BTW, someone earlier said it took two generations for the previous immigrants to be assimilated, that maybe true, but also back then the majority of those immigrants(especially Catholic) went to private schools that were free from the liberal gobbledygook we have today.
BTW, anyone notice that an upside down American flag was not being displayed at a Catholic school.
