I hope other posters will accord me some leeway here, as some definitions and concepts have come up, some I think are outside the realm of non-theists.
Regarding some of these labels:
Atheist--strictly speaking, someone who doesn't believe in the existence of God, or put another way: someone who believes God doesn't exist. To be diplomatic to both sides of the conversation.
Agnostic--someone skeptical about the existence of God or gods; I've seen many agnostics claim that if enough evidence became apparent to them, they would be receptive to believing the existence of God. Not a theist.
I'm not too sure about middle ground types, if there are any.
Hostile Theists:
Dystheist--Believes that God exists. However, this type of theist does not believe that God is wholly, entirely good, and may contemplate the possibility that God might be evil.
Maltheist--Again, definitely believes God exists. However, this person believes that God is without question bad or evil, is actually out to get us.
Misotheist--Another theist, again definitely believing God exists. And regardless of if God is actually good or bad, worthwhile or boring, actually hates God to some degree; whether a passive hatred, or a desire to cause God harm despite how impossible this might be to effect.
The person RDKirk refers to, although they consider themselves an atheist, they are labelling themselves imprecisely as a generic term that is roughly opposed to God. It sounds like that neighbor believes God exists, and it sounds like they are doubtful that God is good, so the neighbor qualifies at least as a Dystheist; further, that person says they hate God, which makes him a Misotheist. So he's both a Dystheist and a Misotheist...but as RDKirk says, he's not too worried about the precise terminology.
It's important to understand who is a theist and a non-theist. There are two distinct challenges there; for a non-theist, if they are looking, they want or need evidence that God exists. If we are talking about, say, someone who was once a Christian, and is now a full-blown non-theist, then they need proof God exists and they need proof that this God is actually good as well. One atheist I talked to said that he considered hatred of God or the view that God wasn't good and possibly evil, as a transitional phase toward Agnosticism and Atheism; and some atheists couldn't fathom getting "stuck" in the hating God phase. Some atheists ask a question on here, and then they have to remind Christian responders that they don't hate God anymore because it makes more sense to them that God doesn't exist; consequently they hatred they feel is impractical because it would be tantamount to hating a character in a fictional novel as if that character was real.
Anyway, if this intrusion is of no help, then my apologies to other posters and the moderators; feel free to carry on and ignore it. All the best to everyone.
