No doubt in my mind, he is a Muslim.
All of the adult members in my family, about 20 people, all agree he is a Muslim. We all agree he is rancid poison.
I believe we're in the early stages of a religious war, the first in who knows how many generations. It is Islam versus Christianity again, but in a sense, it is Islam versus secularism. Secularism is empty; only one (well, two, derived from the same bible, Old and New Testament) source is the fount of Judeo-Christian wisdom, the "thinking-man's" moral credo. Judeo-Christianity is proven; Western Civiliation is not perfect, but it certainly is has created the most prosperous, harmonious, generous, compassionate, and probably ONLY slave-free society in the history of man.
Many good people don't regard Judeo-Christianity as a strength; don't regard secularism and atheism as a weakness; and fail to realize that we are actually facing a religious war -- the first one in many centuries. Sad, scary, regretable ... but true nonetheless.
