True, and historically Christianity certainly doesn't have a stellar record in this regard. But Christian societies have moved on. Islamic societies are still rooted in the middle ages, and they are not going to extricate themselves from this until they stop blaming the West for all their failings and embrace secularism.
I also observe in Australia the failure of Muslims to properly integrate into mainstream society. The vast majority will not intermarry, as the families demand conversion to Islam of would-be suitors. There is a vocal minority who are demanding the recognition of specific Islamic 'laws' to be accommodated in the mainstream law system. It goes on. The problem is that many Muslims, like many Jews, see themselves as Muslims first and Australian citizens second.
It's often hard for people to separate the principles from the practice
