Why is it so easy for so many people to believe that Muslims spontaneously indulge in bloodletting for no apparent reason?

Hmmm
Actually it isn’t all that easy at all. It takes literally decades of indoctrination, propaganda and programming to pull it off. Given that Zionist/jewish interests control well over 90% of the media, the Congress, the White House, Supreme Court, The Federal Reserve, Department of State and Treasury etc. shows just how effective it has been so far.

African continent is not the only victim to European Judeo-Christian greed and genocide – one needs to study Australian “discovery” from some objective source.
