I agree with a past post that mentions how making generalizations on the entire Muslim faith only aggravates the situation and makes it easier for young impressionable idiots to become radicalized. To pretend that Islam is particularly egregious in regards to all other religions is particularly short sighted.
Taking a tour through quotations of the Old Testament will show you genocide, violence, prostitution, misogyny, and homophobia; how is that different from Islam? Catholism and other Protestant ramifications imparted war, persecution, and torture through-out the West for millennia (while suppressing scientific and philosophical advancement to top it off). Old religious creeds like Islam and Christianity are all similarly grotesque because they are all founded on obsolete social beliefs and topped off with years of manipulation.
To make things clear, radicals exist in all religions. This is just the flavor of the month.
