Frankly, I think they've earned the suspicion, and I'm a little puzzled as to why you chose to post their propoganda on this site.
I see. Finally a Muslim groups comes out and says what many have been whispering for some time, but were afraid to state publically for fear of getting their heads cut off. And you portray it as propaganda...nice.
You've got it, Islam the religion of peace, NOT! Read the Koran and learn.
