Islam is extreme. The entire history of Islam, btw, is full of the constant re-conquering of Islamic countries that have made the mistake of growing more “moderate” - by other, more orthodox “extreme” Muslims.
If you’re a guy and a reasonably well-off American, traveling in Islamic countries is probably fairly painless. But living in an Islamic society would be an entirely different matter, and that is what they want to impose on all of us.
Does this mean it’s the first thing that every Muslim thinks about when he wakes up in the morning? Of course not. But enough do, and they have orthodox Islam on their side, which is what makes them so dangerous. Converts are dangerous because they haven’t gotten lax yet - and the cult in its pure form is nothing but a ruthless system of political and social domination.
A cult? It’s more like a prison.
