Talk politics.

The dishonest debate tactic doesn't require knowledge of what's being asked about. Also, I haven't done that. Asking for a citation once for an obscure claim is not that. I don't believe I've ever asked for a citation more than twice (and I don't think I did even that more than once) in a single discussion, and every time it was in response to an outlandish claim that was not common knowledge and therefore I needed to see some source for it.
