I am not a protestant, but you should read Max Webers book, "the protestant ethics and the spirit of capitalism". This masterpiece of socioology explains in detail how a guilt as opposed to shamedriven culture becomes economically more succesful. And yes, we may respect other cultures to live side by side in "harmony". but certain cultures can never expect any economic wealth, at all, unless they change their ways. Countries that sucessfully integrated Northern europe originated institutions, such as Japan, South Korea and Taiwan, not to mention Singapore and Hong Kong, and so on, are all hich tech states that dealt with Northern European cultures. Just compare Macao to Hong Kong for example.
Fully rebutted, you are idealist. I may make pointed claims to illustrate a point and then add nuances, but that does not make me a "biggpot" (bigot?) or a racist.
In fact, genetically speaking, arabs and germans belong to the same caucasian race, and the Iraqi General Izzat Ibrahim al Douri is a redhead with Moustache which could equally well look like a waffen ss general or a member of the Provisional IRA. So, it is not a question about race. Yet, the pan-arabic national socialist movement is the new threat, and it is a national and cultural threat, not a race threat. It is the content of their ideologies, ways to run things and doctrines that should be levelled, not the people. Hence population controls and migration controls. Through admitting people from Tunisia and Bahrain, and not Iraq, Algeria and Yemen, would make that clear.
Even more so , admitting more people from Far East Asia would make the right statement towards this expansive culture that they are isolated. Vancouver is an example where suddenly a third of the population are Chinese, but it works well.
The problem with the arabic culture is its total immersion with Islam, as the language is carried by the Koran, as the bible was carrying latin in medieval times. When some arabs states undergo something like the European reformation, and even their own 30 year war, and split the arab world into progressives and religious zealots, that would be a different situation. Key statistics, arab patent claims, economic growth, ethnic conflicts, population growth, human right cases and so on all suggests this is the worst total doctrinal system living at large on earth, and must be stopped.
Rebutting me would make no difference, rebutting these will.
