I can see the possibilities of one being a follower of Christ, believing He is our Savior and staying in the Muslim culture, even being called a Muslim. Such a person shouldn't be expected to be a baptized Adventist, of course. In places where religious liberty does  not exist there is no other choice. We are not the judge.  But to say this religion is not without its problems is unrealistic. There are many versions of it, some more objectionable than others. Catholicism, in some societies (and I've met Catholics who believe this), has as a goal of world or Christian domination. It is the same with Islam. While we may just want to spread the gospel, there are some religions who want the whole world converted to their particular view of the divine. How Islam wants to do this is a matter for its various groups (some through population growth) and some are quite violent and seek to recruit the young. Religious liberty is out.
