Correct, they are subtler about it, and more effective.
In the US at least, Christianity is far more dangerous than Islam, simply because it has way, way more power here....and there is an alarmingly-large number of people who would be very happy with a theocracy. That is way more dangerous that people blowing up their fucking shoes (or trying to).
I'm all for people believing what they want at home or where-ever it doesn't bother others, who should be free to believe what they want or not. Organized religion says "fuck that, we will spread because that's how we make $." That also includes discriminating against "icky" people like gays just because you cherry-picked a section out (ignoring the parts about divorce, eating shellfish and most of the other crap in there.)
