Fes, you ask a very good question.
I know a Muslim guy who iis very much “americanized”.
He is born here. His parents came here from an Islamic hell hole.
Here are the reasons they don’t abandon islam:
1. It’s family tradition. It’s in the blood. You love your mom and dad, they love you, you respect their Faith. Period.
2. Many muslims know less about mohammed than we do. If they do know what a murderous thug he is, they excuse it, like we excuse Washington for slavery.
3. They absolutely hate Jews for some reason. Hatred is a natural emotion. That religion has harnessed it. They learn from birth that hate is a desired emotion.
So you will see muslims spouse peace, and tell us how wonderful and peaceful it is. They live in america, a majority christian country. This kind of forces them into a peace mode. They like it. It gives them a chance to forget the hell hole they came from, and even romanticize how wonderful it was. No one like to meet new people and tell them they crawled out of a demonic hell hole caused by their religion. So they fantasize.
And if they ever really “Get Religion” those nice, peaceful neighbors will feel obliged to kill you.
I get that it’s hard to leave the faith of their fathers. However, their vicious & cruel behavior & beliefs would do it for me. I would take my kids & flee.
Plus also if you leave Islam, and say become a Christian of simply you just do not believe in anything, then you will be subjected to the death sentence as a apostate.
