The riots were started because of three other cartoons that were much more offensive and were circulated by danish mullahs themshelves(no one knows whether these mullahs themshelves made those cartoons). General muslims today want that europe pass law that bans any blasphemy against islam. If europeans give in that would be disaster... even not wearing burka kind of dress is blasphemy in islamic law... so is listening to music... drawing picture of any living being... not killing animals in cruel halal way etc. etc.
