I think it is probably more accurate to say that oppression encourages 'terrorism'. Of course depending on which side you like they might be called rebels or freedom fighters. If in fact it is even true that most 'terrorists' are Muslim, that would probably only prove that more Muslims live under oppression and poverty. Any ideological framework can be used to convince desperate people to a cause. That isn't some exclusive power of Islam.
Christian America has whacked a few hundred thousand innocent people over the past decade. Terrorism? Nope, just necessary collateral damage, evidently. Honestly, I am not sure which religion can make much of a claim to morality, considering the blood on everyone's hands.
