The sources of Islam in the US are different. South Asian Muslims there are more educated, and from a less hardline religious regions. Indian Muslims, for example, have very often taken part in Hindu or Sikh or Christian festivals in India. They have many non Muslim friends, and are better integrated. They have a cultural and linguistic identity outside Islam.

When I lived in the Middle East, there was a lot less exposure or acceptance of other religions.At best there was indifference. But even there the exposure to other religions was growing. The one notable exception to all this is Saudi Arabia, which is a cesspool of the region in terms of religious tolerance, gender equality, political freedom, and every other socio-political measure. They have done more large scale and long term damage to minority Muslim communities, by funding wahhabism, than ISIS or Al Qaeda.
