I have worked with Muslims over the years....second generation Muslims seem to be OK to work with, they basically have assimilated....
The imported ones like from Pakistan or Palestinian after you get to know them are some of most likely to slit your neck...
They are very anti Jew and when you call them on it... They go bonkers...
For the real wackos, As a Christian I remind them in the end (bible) they will bow the knee to Christ...
The rage is palatable....
I have worked with several (quite a few actually) muslims over the years in Silicon Valley - and I have found all of them to be fine, upstanding people.
That said, I know what the book they claim to follows says.
The bulk of the Muslims are cultural Muslims and they are either operating in 'Muslims in Name Only' mode. However you never really know when they are going to get bit with the 'old time religion' bug.
Ironically we want self-professing Christians to get bitten by this bug, but not self-professing Muslims. The former becomes better persons once bitten. The latter become rabid pit-bulls when bitten.
When I had a shop a neighboring shop was a dofo run by a Moslem fellow. At lunch time he would come over to my shop with coffee for converstation. I didn’t stop work but talked with him while continuing on the machines. I have never been one to eat at work or take lunch breaks. It became apparent by the third visit that the only conversation it was possible to have with the man was on the subject of my imminent conversion to Islam. The third visit, he explained that I and my family probably would not survive as Christians when Islam comes to all of America. I asked him to please leave, that I was busy. He planted his feet there and got insistent that I must convert, that after all, Islam respected Mary and Jesus so our differences were only organizational. I picked up the phone and called the police. He left and did not return.
When the time comes the sons and the gandsonws will slit your throat just as eagerly. Read about the experiences of the Armenians in Turkiye a century ago and the Christians and Yazidi in the current conflict.
For the ones who are from the Middle East in those countries that were formerly Christian at one time you should subtly ask them if they knew that their ancestors were Christian. I’ll bet that many of them do not know because they are not allowed to learn about this in muslim countries. They are taught that the times before Islam was the time of ignorance and there is nothing to learn about it. Muslims who are descended from Christians should learn about their Christian ancestors.
Be tactful with them but let them know from time to time that their ancestors were Christians before the Muslim invasions. Let them know that a foreign army entered their country centuries ago and forced their ancestors to convert to Islam. Let them know that the things that you see ISIS doing were also done to their relatives many years ago.
