I'm afraid neither your religion nor Christianity has exactly a clean record.<quoted text>Christianity harmless? Are you trying to kill me with laughter? The murder of Hypatia, the Crusades, the Church-sanctioned persecution of your Jewish brethren, the Inquisition, the witch and heretic trials... Christianity is a barbaric religion. It looks more civilized now, but it's only due to the islamic influence.
There have been certain times and places where Islamic societies have been more tolerant and humane than Christian ones. Moorish Spain is one examples.
But there have been times when Islamic societies have had a much worse record.
Armed theocracies tend to be bloody affairs whether they march under the crescent or the cross. Of that the record of history is unmistakably clear.
