I would take no comfort from this data.
Militant Islam does not need broad consent or a majority to impose its will as we have seen in Afghanistan twice, the rise of the Islamic state group etc .
A well connected Bangladeshi friend tells me there are real concerns that Bangladesh may fall to Islamists , the way he seemed to tell it was that the Islamist groups already had their hands on the levers of state and I looked it up and that didn't seem the case so I challenged him on it. He basically said that you wouldn't see it in the numbers, but under the surface in the mosques, madrassas, universities, police etc they were taking hold and that a fanatical , well organised minority could easily bring about change as the majority will remain passive and defer to their religious fervour.
It appears to me from conversations with my muslim friends that even for the more secular among them that Islam is a religion that is difficult for them to walk away from and for sure for the majority of them their first allegiance is to their religion, and the less pious are quick to concede their principles to those closer to pure Islam.
As a country we have demonstrated repeatedly that we able to integrate different cultures without major difficulty but Islam is a problem.
