1. I would ask them to link to their claim.

People not being able or willing to back up their claims has become one of the biggest downfalls in societal communication. When I was growing up it was clearly understood that a claim made by an individual needed to be backed up by said individual.

You could look and look without finding and then they will pull something off a reddit sub-forum. Or you could put something forward and they say "no that's not it". The whole debate tactic is shady and is meant to muddy the waters.
