OP seems to be suggesting that people should "do as the romans do", and I said while I agree with the general idea, his suggestion doesn't fit the case in hand.

In this case half of romans are verifiably not bothered [1] by the act of building minarets, then this simple act doesn't signal that people "go there without a degree of humility and willingness to adapt", in his words.

Or you could turn it around and say, if (having ability to) building minarets was such an unacceptable expectation to a point of painting one as a colonist, it wouldn't gather the support it gathered from the local community in the first place.

[1] to the extent of participating in a political process to explicitly disagree with the ban.
