I'm sorry, David, but it's quite ironic coming from a Jew.
What is the actual argument you are making?
You know, I'm a little confused with where you stand. You're very proud of being a Jew, and then you're going with things as "our birthrates", while referring to Germans or other European nations. I wonder how you define a "German" of a "Dutch" in this particular context. Or what is a "native". Are we talking citizenships from birth or purely ethnic origin?
I'm confused because putting it this way sounds like what the very antisemites were saying about "kicking the Jews back to Palestine", "Jewish influence", "Jewish domination" and such BS. And yes, we both know there was a time Jews made up really sizeable portion of European societies and they were rightly protective of their traditions, religion and values against intolerant neighbours.
As far as I see it, you're both a Jew and a Dutch, so I can't see why you can't have somebody who's both a Dutch and a Muslim of Arab/Turkish descent. Sure, you can say it's about the degree of assimilation to European societies (which doesn't and shouldn't mean giving up your cultural heritage), but if we start to push those less assimilated out, we just don't know where it'll end. There are always going to be assholes who'll want everybody out and you'd just give then a perfect launching pod.
