Mixed thoughts about this one. Reading the Koran was certainly revealing to me about what a hateful and vile religion it is. Of course, some may read it and say “wow, I want to be a first class citizen and murder, rape and plunder my way to paradise.” It’s a tough call.
I don’t need to smell crap to know that it stinks.
In Russia, I imagine it's an easier call. Translated Korans are used primarily for recruitment. With a population that was raised primarily in an atheist culture, the people would be more vulnerable to the "sales pitch" and less likely to read it and see how horrific it is.
