We are learning that the little country in Europe appears to be a stronghold for Islamic radicals. Why is that?
One has to look at the history of a country divided by language and customs for centuries. When has Belgium actually had unity? You have one group speaking Flemish, another Walloon, and yet another German. It also has two distinct regions with distinct customs.
Do people who live there consider themselves Belgian? Sadly, no.
And what happens to the immigrants who come there to live? They resort to enclaves of their fellows and adhere to the same beliefs they had back home. So, with lack of melting into one society, we have a nation divided.
Just what progressives are trying to do to the USA!
