Not true. Japan allows them in very limited numbers. I worked with some when I was there. Needless to say, they weren’t the jihadi variety. At least one of them was very fond of beer.
If there were no Jihadi variety Muslims; the world wouldn’t have the problem with the Muslims they do today. One bad apple and all that...
I lived in Turkey as a teen and it was no problem because they were moderates who just wanted to live peacefully like anyone else.
If Islam had a reformation and with a unified voice rejected the radical Islamics; the world could begin to heal from the Islamic atrocities. Especially if the Muslims helped to identify those who were the problem children among them. In time the pull of that life would fade from memory for everyone other than what would be read in the history books.
