Christian "You worship death. Your existence is hopeless, you are destined to die, your world is dead, dead, dead"
Athiest "Aren't you basically focused on the 'afterlife' aka 'death'"?
Christian "You have no basis for morality. In essence you are in denial that you are following Christian morality"
Atheist "Excuse me but do you own slaves? Do you think divorce should be forbidden? Why are you so focussed on your own wealth and supporting the use of violence"
Christian "If God doesn't exist, there is no absolute standard by which to have logic"
Atheist "What the hell are you talking about. Go away. If your sentence were true, we would have language. You've simply introduced a new axiom and shown that you have no logical basis for any of the claims you are making."
In this thread, take Christian critisms of atheists and throw it back at them with irony that will go over their heads.
