Generally, I am not a fan of immigration, and I certainly know that "good Muslims" are incompatible with the west.
If, as has been stated, 10-20 percent of Muslims hold what are fundamentalist ("radical") views, then all the nations allowing hundred of thousands of Middle East peoples in are setting themselves up for endless chaos that will only intensify as the decades pass.
Fact is, the Middle East has been and continues to be, in general, a true hellhole on Earth, resulting from, at its core, the religion of Islam. It's no coincidence that wherever Islam plants a profound root, trouble, chaos and mayhem ensues.
Heck, if even ONE percent of the Muslim global population (the better part of two billion) is fundamentalist, this translates into millions who swear the non-Muslim population as their mortal enemy. To be mowed down in the push to make Islam all-encompassing, everywhere.
It's a cruel world. It is very sad how things are. But facts are facts.
The threat of Islam is real. Not all Muslims ... but Islam and those who are, again, "good Muslims".
I very much dislike all religion, but to use Christianity, or whatever, in a comparison is nonsense. If you don't know why this is, well, you need to button up and do some research/thinking.
