You would be surprised how many practising Muslims left their homelands to avoid being preached at (and to live in a society where they can just do their own thing). They are the ones most annoyed at current policies.
Non-practising Muslim immigrants are also persuadable, but are susceptible to the Woke virus. The % is small so far, but something to keep an eye on.
Then you get Sharia-bros with seven kids on welfare and a hobby of stalking their neighbours, usually those they think are Muslim or at least should be.
F--- those guys, but they are a small minority so far.
Govt working on that.
