This just seems like a rather clever permutation of ad hominem.

“The reason I won’t refute your argument is that it is so incorrect that it would take me forever to explain why.”

Not really. Ad hominem is directing the subject of your argument at the person instead of their ideas.

Brandolini's law is more like the adage, "a lie can travel halfway around the world, while the truth is lacing up its boots." It's very easy to spout correct-sounding lies in such a volume that countering them becomes an academic challenge.

You're looking at it wrong. It's that there is so much bull out there that it would be impossible to refute it all.

Or as Pauli said, "Not even wrong."
