Are all Muslims really sure that Islam is a religion of peace?

No Islam is not a religion of peace. I know because I lived among them for 3&1/2 years in Dearborn, Michigan. If they are not fighting and killing infidels they're doing the same to each other. And I'm sick of hearing about what a bad thing the Crusades were. The crusaders wanted to liberate what they considered by their religion as the "Holy Land." The muslims on the other hand have been on a rampage of conquest since their beginnings. Just look what the Turks did to the Eastern Europeans and the Armenians. It was the Turks slaughter of the Armenians that gave Hitler the courage to go after the Jews and others. The bottom line is if the muslims go into an area they immediately start trying to exert influence and take the area over. They start quietly as the minority and then as their population increases they start agitating to take over, by violent means if necessary. Look what has happened with the muslim thugs in Australia recently. It wasn't Australians killing muslims but muslims killing Australians. Australians for crying out loud! I have had many friends over the years who are muslim. As individuals I treat them as I would anyone else. But I do not allow myself to be so naive as to believe they would not forcibly convert me if they could. In Christianity we believe in free will. In times past Jews and others were forced to openly convert. But in Chritianity one must repent of their sins and accept Christ of their own free will or it is not genuine. I am not a bigot. I am one of the most tolerant individuals in the world. I am a liberal Democrat. But I also believe in telling it like it is.
