Analogy time
Theists: Cat is dog.
Atheists: I don't completely agree or i disagree.
Me: lol cat is cat,cat aian't dog lmao.
Theists: Oh. *runs to the room crying*
Me: ._.
Atheists: Haha look at theist noobs,lets get outta here. [this is the appropriate response :P]
Atheists: Haha look at theist noobs,they are so wrong,lets not get outta here and stay here. [this is the inappropriate response :P in which case atheists have the burden of proof -because theists are no longer making a claim,so you're just sittin there rejecting a claim that isn't even made *derp* so you're the one making a claim in that case]

[i specifically used "noobs" because you are a 5 year old and i'm told 5 year olds play COD]

Better Analogy time
Theism is the mother.
She gave birth to her sons atheism,deism,agnosticism,gnosticism,polytheism,ditheism,pantheism,etc.(gawd lady xD)
Atheists: mommy can't reproduce ; _ ; i'm adopted.
Theists: no lol we aer her cheldrn.
Atheists: no you fucking idiot!i checked.. - she's a man!

So Atheists are saying that Theism is a man and theism couldn't have taken Atheists out of her vagina(because obviously she doesn't have one).
If Theism is indeed a man then Atheists cease to exist(just like how the "Mother" cease to exist)because a man can't give birth xD [ps: adoption is a big NO NO in the analogy]
