I will prove to you that God exists

On another forum, I pointed out a fallacy in one of his replies.  His response was to suggest that he could find fallacies in my posts, too.  I think rhetoric is a more telling master for him than logic.

You can find fallacies in any posts not just yours. The beauty is most folks in here list one of these but never explain why the fallacy applies to what I said.

That's a lie, I have explained countless times why your attempts to reverse your burden of proof, is an argumentum ad ignorantiam fallacy, and this claim about the posts of others is again fallacious it is called whataboutism, it is a form of the tu quoque fallacy. Not only is your accusation unevidenced, and therefore groundless, even were it true, your argument would remain fallacious, this illustrates clearly you have no understanding of what this means, or it's importance, and this even after I have explained it to you several times. 

The one they don't mention is the fallafetish fallacy. The obsession with finding so called fallacies. 

I have not mentioned it as it has not been used that I have seen. I suspect you have no more grasp of when and why this fallacy applies than any other, but you seem utterly unable / unwilling to grasp that disbelief of your claim, need not, and in my case certainly does not, involve a contrary claim, this is also the error in reasoning you have used to produce countless straw man fallacies, to misrepresent what I and others have said. 
FYI, I have no idea what relevance that list has to your fallacious argument, or your lack of integrity in acknowledging or addressing this fact, or what it means for your argument, though we can I suspect infer from this post and your referencing a fallafetish fallacy, that you still don't understand this, even though I have explained several times what it means.
