What a truly spectacularly stupid claim, did you not watch cartoons with an “evil” character as a child? One can hate a hypothetical construct, if the superstition being peddled contains obviously pernicious beliefs, then of course it would be rational to hate the concept.
I smell BS, and I’ve read two posts of yours and they both scream trolling.
Well that trivially true assertion neatly evades the point, you do seem to have a knack for ignoring the thread topic and preaching, I can’t say I care for it.
Only if one doesn’t understand that many people peddle just such a deity as real, and also fail to grasp that a debate can be based on a hypothetical notion. Just because I don’t believe in any deities because no one can demonstrate any objective evidence they are real, or even possible, does not mean I can’t debate the claims theists make about them, or hate such concepts if they are morally loathsome.
Wow another trivially true fact, have you never read any books that had fictional characters in them whose turpitude made them loathsome? A bit like the way the biblical deity is loathsome to me, even though I am an atheist. I can still read the claims and see they are morally repugnant, all the more so since it is claimed to be morally perfect and possess limitless power and knowledge, making its culpability more absolute, albeit hypothetically.
I don’t agree they are mutually exclusive, since a concept does not have to be real in order to engender anger, especially since the concept has very real consequences in how theists behave and treat others.
How are you measuring anger here, as this sounds like pure assumption to create a response, and how are you differentiating between anger directed at theistic behaviour and revulsion at a deity that is depicted in the bible as morally repugnant?
And you tracked us down here to tell us, I find this claim as dubious as many of your others.
No one is pretending the first two, but the last one is just a straw man you’ve created, and seems to be suggesting atheists secretly are not theists, a very unoriginal lie apologists often try to peddle here. I can find the biblical deity utterly loathsome without believing it exists. Though to be honest as @Get_off_my_lawn has suggested, I think the anger here is predominantly coming from you.
Well exactly, I was going to give him a little more rope on that one, but yes you are precisely correct.
Then you should have been more careful to avoid that precise tone in your opening gambit, but I suspect your faux indignation is all part of the carefully constructed act. Nothing you have posted suggests you have any interest in honest debate.
Then accurately define your deity, and demonstrate some objective evidence it exists outside of your mind? The confusion is of course your own fault as you have failed to make your position remotely clear beyond the broad claim to be a theist.
Oh dear I suggest you consult a dictionary.
Atheism is defined as disbelief or lack of belief in the existence of God or gods. Whereas agnosticism is defined as the a person who believes that nothing is known or can be known of the existence or nature of God. So clearly they are not mutually exclusive, and as @Nyarlathotep says it is ludicrous to claim they are. For example you have told us precisely nothing about the deity you claim to believe is real, so of course I must rationally withhold belief from the claim, and also remain agnostic about it.
Quod erat demonstrandum.
Theism as a belief is the affirmation of a claim, atheism is simply the lack or absence of that belief, so there is no parity. You are making the claim, and brought it deliberately to people you know don’t share the belief, so it is for you to properly evidence it.
But not mutually exclusive, obviously.
Your belief is defined in your profile, it’s hardly anyone else’s fault if you have failed to offer any cogent or accurate facts beyond the broad claim.
Tell us again how angry we all are… 
IT’S IN YOUR PROFILE!!!
This is a tired old trick many apologists have used, to be as vague as possible, and then blame others for not knowing magically what the details of your superstition are.
