You are referring to the potential roots of the very issue and why certain groups have been forced into immigrating to other countries.
What you line out might all be very true but it still doesnt justify the intolerance and resistance these groups have towards the Western standards of the countries they migrated to.
Again I purely speak from my own experience growing up and having lived in The Netherlands and Germany for 25 years, in a society that was tolerant and open for a multicultural approach.
What is erupting at the moment, has been coming for a long time and will undeniably lead to the collapse of Europe. I do not doubt, it is all by design as the borders to all first world countries, including Australia are wide open.
