To further that question, Why do those types run away to the west, Quite audaciously sport flags of western nations all the while seeking to destroy that very Western civilization and a establish fundamentalist Islamic utopia they and perhaps their parents ran away from ? Quite a conundrum
They desire to live the pompous 'western' lifestyle while maintaining their pretentious religiosity in order to have something to look forward to in the 'hereafter'.
Hypocrites, who want to have the cake and eat it too.
Are Sylhetis more conservative than Bengalis? I understand that Sylhet used to be a part of Assam before 47.
What about Rohingyas? Are they more rightwing or more moderate than Bengalis? I assumed the eastern you go, the lesser the hardcore element becomes.
Sylhet is home to many a mazars and Sufi darbars, the population is a bit more pretentiously religious....
People in our countries aren't really pious, in the sense that they follow God's commandments, no, for them piety is telling the neighbours daughter what to wear; totally unsolicited advice (which apparently paves the way for you to get it good in paradise).
Whether Sylhetis are like that or whether it's an affect of the many shrines and rabid mullahs, I don't want to say, I don't enjoy being mistaken for a racist and so on....
About Rohingya, yes, they're alot more religious, but remember to hold onto your culture in a genocidal land that hates you means you need to hold everything dear to you close by and that's why they're a little more religious than others.
I don't think there is any geographic index here at play, for instance Chittagong is the division with the highest proportions of non Muslims in Bangladesh, indeed my ancestral district of Sitakundu is 30% - 35% Hindu and we all get along just fine,.. we have a Shakti peeth in our locality (a pilgrimage site that Hindus from all over come to visit).
It's just depends from person to person, their upbringing and the elements they're exposed to, but mullahs and mazars are definitely a factor.... The more of those you have around you, the more pretentiously religious you get.
