I agree you are correct, Marcus. However, as a counterpoint I would like to offer that Jews are also not a race. Semites are a race, but not Jews themselves. How strange it is that most Americans recognise one as a religion and the other as a race!!

It is strange, in a way. However, Judaism is generally tied to the Jewish gene pool, with very little in the way of conversion to Judaism. The word Jewish can mean the religion, the gene pool, or both. By contrast, Islam is not tied to genetic inheritance, but to the religion only.

The tenets of Christianity (and Judaism) say precisely the same thing, yet we do not see this behaviour among Christians (or Muslims) in developed nations.

Judaism is not at all a proselytizing religion, but rather it discourages it in many ways.

Christianity does include the explicit instruction to convert, but does not have, even in the most extreme forms, the instruction, explicit or implied, to enslave or kill those who do not convert.

That is not to say that Christians during the conquest of (now) Latin America did not kill or enslave those who did not convert. They did. They also enslaved those who did convert. The orthodoxy of the religion, and the religious texts, however, did not mandate this behavior. The Conquistadores were just greedy and sadistic.

Please bear in mind that I specified the orthodoxy of the sects, not the average Muslim dictate the conversion, killing, or enslavement of non-Muslims. Clearly, as in every religion, people do not necessarily adhere to the mandates of orthodoxy, and there are always many who patently reject it.

However, surveys around the world, particularly one survey of Muslims in Britain, indicate that almost half, and sometimes as much as 95% of Muslims surveyed advocate for imposition of Sharia on all people in every society where there are Muslims.

Sharia is the problematic aspect of Islam, and in Europe, (France and Britain, particularly) we can see in action the difficulties it inserts into any culture that has a significantly large population of Muslims.

When large numbers of one culture/religion move into a nation with an incompatible culture, there is guaranteed to be some percentage of immigrants who refuse to assimilate. The larger the immigrant pool, the larger the percentage, and the more influence that culture can impose on the host culture. If that influence is one of intolerance of aspects of the host culture, then there will be conflict.

The US is a melting pot that seeks to assimilate immigrants while simultaneously creating a syncretic culture. We actually have cultural mechanisms, unlike Japan (or most of Europe) to help accomplish this over the course of 1 or 2 generations. Granted, political correctness has made many of these mechanisms less effective, especially in the face of an unprecedentedly large wave of immigration. (Some US government estimates are that 14-16% of the US population are permanent legal residents or naturalized citizens)

Japan, like Poland and Hungary, (and for that matter many other nations in Europe, like France, Greece, Turkey, & the Netherlands) does not want to be a syncretic culture. They specifically want to maintain their national and cultural identities. Given that, it makes sense to exclude people who want to import their own culture (including their religion) as they immigrate.
