Take into account the primitive, cruel and barbaric way of their culture
Like burning people wrapped in pork skin? Yeah, probably.

Those who fight are always scarier than those who sit around doing nothing. Sitting on your bum saying sweet, nice and peaceful things is looked upon brightly in Western societies, while saying one should fight is frowned upon by most. That's because most don't know how their 'freedom' is earned.
Huh? You fight? Sitting in your bum saying salty, not-nice and violent things? I should give you a medal.

Plus, how do you know I don't fight? You know nothing about my life, I could be....say....Subcomandante Marcos posting from Lacandona.

On the other hand, the text above I just quoted, the fighting one, could easily apply to a terrorist. Plus, previously you said:

But, sometimes, it's also good to strike fear.
Isn't that what the terrorists do? Strike fear to get to a cause? Then, you are defending terrorism against terrorism? If for fighting the mosters you have to become a monster yourself, please take Nietzsche out of your signature.
