I would ban all. However, that is not Trumps position.
Apologies. I misread your post.
I thought you wrote that most terrorists are not Muslim.
The problem is we are not just dealing with pure terrorism here. We are also dealing with opposing cultures.
I am by no means pro-religion, and I do not wave a flag which says Islam, or any religion, doesn't have huge flaws. And yes, I am skeptical of some parts of Islam, particularly how it is used to implement far-right oppressive practices in countries of high Muslim population.
However.
The vast majority of Muslims follow the religion because of cultural reasons and live peacefully by it. I have no idea which surveys your guy in the video was referring to throughout, because he not sourced where he was finding how many Muslims lived in those countries. I'd be interested to see them, though.
Muslims, Christians, Jews, and people of other religions, live peacefully all over the world. British Muslims are a British. American Muslims are American. They still belong to a country and follow the laws, the rules, the etiquettes and the ways of life of that country.
