What about when Christians do it? Usually results in a viscous slave trade (Africa and the Caribbean) or genocide (colonization of North and Central America).
One side claims there is something fundamentally wrong with the religion of Islam and points to passages in the Quran. That side should, then, also note the fundamental problems with most major religions and point to passages in the Bible (old and new testament), the book of mormon, and other holy texts. But this side does not do that. That indicates to the other side that this is not a logical argument based on genuine fear of a hostile culture, but merely a race/religion war in different clothing (christians fearing muslims).
