I agree that they’ve been waging holy war against Jews and Christians since the 7th century. But that doesn’t mean we need to descend to their level. Let’s just be disciplined enough to view it as a justified self-defense and leave the Christian holy war out of it. It gains us no advantage. When we fight for justice we are fighting for God, but Justice will do as our justification just fine. Is there any harm in leaving it at that?
Be wise as serpents and gentle as doves, some great Religious Teacher once said.
Descending to their level would be deliberately attacking their women and children and making no distinction between innocents and combatants.
Make no mistake: we need to understand that we are already are in a holy war. It was predicted by Jesus and written about by John.
