Islam and Jihad

Because I've been reading about Islam lately, I've been trying to clarify my answer to a certain questions:

Is violence (radical Islam/jihad) inherent in Islam?
Yes and no. Muhammad taught both violence and peace, both intolerance and tolerance. Because it is a man-made system of faith, it is not perfectly consistent. Muslim clerics throughout the centuries have taught, from the Koran and the Hadith, a variance of doctrines. To say that Islam=violence is wrong. To say that Islam=peace is wrong.

I think I wanted to be able to say "yes," absolutely. I'm not sure why, yet.
