"Clearly Islam has serious faults..."
So now Koran-inspired Jihad and murder of infidels is nothing more than a "serious fault???"
Please, by all means, let's tell the families of those victims killed this past Tuesday that what happened wasn't really an act of war, rather that it was just "their bad."
I'm sure they'll all feel better knowing it was just one big mistake. </sarcasm>
But since you bring up this story about Lebanon, please show us some authoritative documentation for it. Perhaps it's true, but someone's "Geocities" website proves nothing. Bear in mind that there is the question of blood types to be considered. Taking everything into account, it doesn't seem plausible.
My point is not that Islamic countries are wonderful places to live or entirely filled with wonderful people, but that one can find bad points in any culture or religion, if one surveys their entire history. Remember those killed in the Wars of Religion or the Cathars and Albigensians ...
We will have to do what we will have to do. Stirring up excessive hatred or contempt or anger doesn't seem to be called for.
