Sure the answer was obvious, JLM. Islam refers to the religion, Muslims refers to the follower. That is why I was surprised that you asked such a simple question (what is more, kept on asking it), that is not like you.
Obvious to you maybe. I've never pretended to be cognizant about different religions and have not studied any of them. Islam, Muslim are just words to me, but I was told by someone that Islam is the pure religion, Muslim is just a watered down version so that's what my knowledge or lack there of was based on. But to get real S.J. my understanding is no more astounding than your "understanding" of Liberals and Conservatives, which is approximately the same as my understanding of foreign religions.
