.reject charity for others, embrace a 15th century tent culture, contribute nothing to medicine, technology, or the arts, and provide no viable targets for military retribution?

I don't think I have heard or seen anyone doing these things...is that your suggestion?

If you have not seen the news then you have not seen these things. They cannot give charity to anyone who is not Islamic and for that matter if they are true to the Qu'ran then they should make every effort to isolate themselves from all infidels.
