Generally it's Needy" people they go after.....that's what the Islmic Community centers are about...they not only Convert people there but the lure and bait is always to assist poor people they have interest in...they 'target' school teachers, police officers and military people hard on their luck....both of which they know and have access to guns when the time comes...and can and do educate the new arrivals in their Mosques.
I would advise you to be cautious with the very nice family next door. If he attends Mosque and reads the Koran he is not the exception....and even if he goes to a Christian Church...the Islamic agenda is to get their people into the Christian churches.
This is why Islam is such a dastardly deceptive and all encompassing ideology that has no nation boundaries because their goal is to infiltrate and conquer....as silently as possible...until all are positioned as needed.
The African Muslims will be the first they use to incite riots etc....most are illiterate, can't and won't learn the languages and therefore unemployable for the most part....easy to manipulate. And there are vast numbers now coming into the nations....
No, my neighbor does not attend a mosque. Thankfully, there is none in the neighborhood as far as I can see. Near my little apt. in NYC there is a filthy one about twenty blocks from my house - a storefront. The Berbers are generally good people. They were the subject of a movie - the title of which I’ve forgotten. It’s about French priests in Algeria who were murdered by Arab muslim invadors. It’s based on a true story. It’s a French language movie. The Berbers were the good guys in this case.
