I would think, though, that there isn't an effort to convince us that the roots of all those murders are actually benign. Most people think of hard drugs as a 'bad thing' to become addicted to, etc. However, there is a lot of political and social pressure to view Islam as benign. In other words, we're encouraged to not think of Islam as a potential social illness, even though we think of lust, greed, drugs, as being so.
If there was a large social movement to view hard drug use as 'acceptable', I'm sure similar tactics would be used.
