To those who don't share the same beliefs as the Evangelists, it looks disingenuous.

True, and I understand this, especially since there has been some very bad evangelism in the past (like the crusades). I think Christians have to be very careful how in how they approach evangelism and make sure they aren’t doing more harm than good, especially in places like Iraq.

There are evangelists who go into countries without bothering to learn about the people or understand their culture. This is really bad all around and only breeds mistrust. However, a good evangelist learns about the culture so he or she can approach people in a way that they understand and be as non-threatening as possible. An good evangelist must always be interested in the welfare (both spiritual and physical) of the people that he or she is trying to reach; anything else really is disingenuous no matter who’s looking at it.
