This is a very interesting (but long) documentary on an amazing viking sword blade that was ahead of its time in europe. A further interesting aspect to this documentary, is that the sword blade was made from the Islamic civilisation’s industrial methods and processes; including the import of processed raw materials. A fascinating, and factually detailed documentary.
The Muslim Debate Initiative 
Islamic tolerance is an oxymoron: if you have ever lived in an islamic country you will know there is no tolerance of non-muslims, who are always second class human beings to begin with, unclean, infidels, who must live in compounds in some muslim countries and who cannot live “normal”lives in most muslim countries as ex-pats with the restrictions put on movement and activity permitted by the muslim state.
