I just consider them warriors for Islam, and act accordingly. (Watch, avoid)
In the area where I live they have been around since I was a child. I guess I don’t give it a second thought.
I also live in a community where there is a Hebrew school and a bunch of hassidic jews. I have been approached by more aggressive hassidic jew school kids than muslim kids.
But, we all know it’s the Mennonites that we have to watch out for. Those folks will slap you in the face with a blackberry pie. (Just kidding...I love their pies.)
