No flaming please.
Short explanation of each option:
Theism
Trinitarianism: The belief of one deity with three forms. Mostly held by Christians.
Monotheism: The belief of a single deity. For example, Christians, Muslims, and Jews.
Polytheism: The belief in multiple, distinct deities. For example, Hindus.
Pantheism: The belief that the universe and god are one and the same.
Antitheism: The belief that there is a deity, but that they are evil and are to be fought and not worshipped.
Agnosticism: The belief that there may be a deity, but are uncertain about the matter.
Atheism: The belief that no deities exist.
Apatheism: A lack of opinion on the matter.
I, myself, am an agnostic. I don't see any reason to believe in a deity with 100% certainty, but the possibility certainly exists. I am not a militant agnostic, and think that personal religion is a good thing, but I much dislike evangelism, and believe that religion should be purely personal and should not affect the lives of anyone not of your faith.
