Omani's are a cultural peoples, they are very warm to guests and well mannered. Some attribute that to religion, some to culture. All religions are dying however, and we should let them go into the past. There's no need to replace them with Deism or whatever. I miss the days when religion used to be about a pursuit for truth. Nowadays it's just a interest or hobby or mask people wear. We need to change that and stop resorting to old ideas. Let's come up with new ideas about our purpose in life. By philosophical means. The world shouldn't put up with organized religion which leads people into major misunderstandings on their purpose in life, which also leads to social ineptness and lack of integration with reality. There are some lucky people who left organized religion early on, but it still left an scar and probably influences their life if their immediate family follows it.
From what I've noticed, Sufi's seem to be very spiritual people. The content of Islam is still Sunni Islam. The people themselves do observe prayers as much as they can, but culturally lead Western lifestyle. Which basically turned me off, it means they don't believe in religion enough for it to get in the way of daily affairs, dating, partying, etc....Salafi's on other hand usually are Salafi just to show off. Both annoy me, I don't like religion in the West. Overseas it mostly doesn't work either. Which is what extremists keep complaining about, that their people aren't implementing God's faith and hence they make it their duty to violently restore it. Just like past Muslim figures.
It depends on culture, out of Arabs, I've only seen Islam work well with Omani's and Palestinians. The rest either aren't religious but liberal and more nationalist, or technically are religious but not to point where it threatens ruling body. Those are the ones that have trouble with militancy.
