The same can be said for Christianity. The problem is that most theologies (especially the Abrahamic ones) can be interpreted however you want - and Islam is easily interpreted as violent and agressive. However, this does require an interpretation, which implies that the religion is not at the core of the issue (or at the very least, not the only thing at the core of the issue).
Incomplete reasoning. Islamic terrorism has become a force in the modern world do to sociological, historical, and cultural factors. Ignoring the first two to focus on the last will only perpetuate the problem, and will, in fact, probably make it worse.
Hitler and Stalin were both authoritarians. I suppose they were good buddies, hmm?
Not scared? You ought to be. Me, I'm plenty scared. Fear, after all, is our most basic and (arguably) most powerful survival mechanism. Without it, the subconscious would lose focus on survival and would instead focus on some biproduct of the other basic emotions: anger, sadness, happiness, and disgust.
Which of these, then, do you feel?
I would hope so.
Any particular reason for this, or are you just flexing some bravado?
It is not whether terrorists exist, but rather what their motivations and capabilities are that is in question.
