How many Muslims do you actually know? I'm guessing not many, in fact probably about none. Have you ever been in a mosque? Do you really even know what you are afraid of?
Only a handful really know. Seen a whole neighbor go "down the tubes" though due to Morocco Muslims moving in en masse over a course of some years. No one I knew were radical, though a neighbor was, maybe, a bit suspect. But the ones I really know only the wife still practices and her husband, a retired professor, is very secular and says that Islam is a backwards religion and the best thing to happen to Pakistan was the British and that the whole region has progressed backwards from when they were young mainly due to Saudi influence and money (they fund a lot of the schools and groups that promote the most virulent form of Islam.) He will never return. She still goes back sometimes to see family but says now she never leaves the family compound, needs to wear garb from the airport to her family's village, etc and that as a girl she didn't have to wear garb, could go to movies and shop without harassment, go to school, etc. No more now. People raised in this backwards culture are what we are told we must import. I must admit some surprise how fashionable it is to support "refugees" from the leftists, and even feminists, considering their views (and actions) on women and girls!
The only mosque I've been to is the large Islamic Center in DC on Embassy row but didn't go to pray to Allah or participate in services. I wonder if they host a seder or allow Christians to hold services there? We allowed Muslims to hold services in our churchs, such as the National Cathedral. Currently many churches are helping or hosting "refugees"- but many mosques and Islamic countries won't allow them in. And what about other illegals who aren't Muslim? What is the excuse that we must allow them in also? We aren't "bombing their countries," for the most part, so that excuse doesn't hold water. Why should some El Salvadoran or Mexican get free healthcare, housing, transport, and legal aid over and above what an actual US citizen, or even veteran, get from their government? Why should some "refugee" or other illegal not be held to a standard of other emigres? Pass background checks, have name verified, have paperwork, be free of disease and prove vaccinations, etc?
