Does it make any sense to ask what is the case for atheism?

[Whateverist]

If atheists do not define what atheism is, and the case for it, then someone else will.

They do that whether we do or not. This is why there is no debate. They are too deceptive to have an actual conversation.

I agree with antithesis that they will misunderstand what atheism means regardless. If anyone thought that reason would be in play, more of us might make the effort to explain why we think atheism makes sense. But if you expect reason from those for whom the basis for believing is wish fulfillment, you are unreasonably optimistic.
