No pal. You are the bullshitter. You made the outrageous claim. You need to support it.

Think about what McGrath of Harlow said.

"I am not aware of any claims..." might have been a way of avoiding that trap.

Even after that you claim that the burden of truth is on me. You have given yourself license in an argument to claim everything that is unprovable supports your side. Be careful with this. It will lead you to delude yourself. It may even lead you to think that your Bull Shit arguments matter.
