Bingo! You pretty much nailed the real difference here.
It is a clash between cultures - not skin color. Christianity and a strong Christian influence usually makes all the difference in the world in these things.
In the case of France and Europe, it is Muslim versus the Infidel (Western Europe has pretty much forsaken Christ, except in the nominal cultural sense). There is genuine invasion and jihad happening here.
In the U.S. the clash has devolved to an ungodly feral welfare and criminal class of blacks (tainting decent blacks) versus everybody else including black Christians. That state of unhappy affairs has a lot to do with drugs, the disintegration of the black family, and the depredations of the Progressives who prey on black Americans to bend them to their political will - most recently dating back to the Great Society, but before from slavery. Then, official black segregation of 2nd class status was instituted and enforced by the southern Democrat Party dating from the 1800s.
One also cannot ignore the unparalleled social destruction caused by illegal immigration and the importation of 10s of millions of semi-illiterate people with allegiances to other counties and non-American cultures. This is also a result of the scheming for power by the Democrat Party and other Progressives, with the approval of greedy, unethical employers and weak GOP politicians.
...(remember Congressman Billy Bob?)
Yes. Unfortunately, he (John Armour) had colon cancer surgery and unexpectedly died under post-operative care. His passing was a great loss to this site and legal common sense.
But to be clear concerning the article posted, I grieve for Europe, and frightened for the continent, especially Great Britain. This is indeed madness
