Reply #7: I suppose it depends on the neutrality of the adjective

[wuushew]

I would consider "Islamic" a neutral descriptor when placed in front of a term that has shared meaning between two or more parties.

A practitioner of Whahadi Islam would not deny what they practice is Islam nor that it is fundamental in its nature. The label therefore is largely the same thing in different languages. Therefore our word for a particular group is not inconsistent with self-ascribed titles or identities.

When dissimilar descriptors or combined it is easy to infer intentional insult.
