I offend...

I have a friend who sends me religious items frequently...I understand. And recently, I was forwarded another of those mass-hysteria emails showing muslims demonstrating in England. Granted, some of the slogans of the demonstrators were negative- some would say threatening- and the email included a message from some other fear-monger ("Americans need to know! You need to forward this to everyone. These pictures tell it all!"). Um, yes...
This inspired me to reply "What have American christians done to diffuse this sentiment?" I know it will most probably be interpreted as insulting to his religion, which was not my intent. My point is, do all christians think all muslims are out for world domination? And if so, how is that different from the quest of christians worldwide? Is it a difference of domination method chosen or simple ignorance of the situation... doesn't the attempt offend the other?
