Yes, that's my projection. Sorry for the ad hominem argument. It just smelled like a rhetorical trick, so I got carried away. I also admit my post was a bit trolley (I expected down-votes and no reply, actually). But I don't think it was nonsense. I merely stated my (strong) beliefs without the usual "I believe" disclaimer. There's a reason why:
Either God exists, or it doesn't. Of atheists and deists, one group is wrong. As a matter of fact. As you know, I don't believe in God. If I were polite, I would stop there. Same thing for a deist. We could have a conversation, say "I (don't) believe in God", and it would still look like we "respect" the other's beliefs, and therefore we respect the other, period.
Trouble starts when I say "God doesn't exist" (it really doesn't). It's offensive. It makes too obvious that I think deists are wrong (they really are). Such a direct attack to their belief is of course not polite at all (yes, I am not polite). Politeness is secondary, however: we face Freaking Real Death! I bet many would like to solve that problem (and there are slim hopes that it will eventually be).
On the other hand, a deist that really believes in God, should tell me that it exists, that I'm wrong. Being polite is again secondary. Hey, my non-believer's very soul is at stake! I certainly wouldn't want to Burn in Hell for, say, wanting to be immortal.
Another point. You said earlier:
> […] "Is there a God?" is both unprovable and unfalsifiable. […]
This is weird to my ears. I assume that for any thing that have observable effect, science has a hope of detecting (and proving the presence of) that thing. God is no exception. So, if you're right, then the existence of God doesn't have any observable effect (by contraposition). Then, belief in God, an observable effect, isn't linked in any way to the actual existence of God. Meaning, belief in God has no valid justification.
Plus, the way that typical monotheists religions depict it, not only God is observable, it has actually been observed. For instance, any miracle God have performed should have a hope of being detected by archaeologists. (Unless God cleverly erased the evidence but I don't recall anything like that on the Bible. To my knowledge, it isn't written that God evades science.)
Plus, God is almost always depicted as omnipotent, omnipresent, and omni-benevolent (let's live aside sentience etc.). Well, those three characteristics combined should be sufficient to have a pretty big observable effect: living in the best possible world. If we don't (it's pretty clear we don't), then something is off.
So, saying that the existence of God can't be tested strikes me as an extremely weak justification for belief in God. Weaker that plainly stating that God exists because three famous, old, Holy books say so (authority can be a valid argument).
