I'm not sure what that's supposed to mean, but I assume it has something to do with arguing about choosing the alternate source of fact on top of the discussion about criticism of wikipedia, which is used as a source of fact.
This is not a winnable debate, but differing views exist.

The dubious nature of wikipedia's editing is recorded within books and articles from over the last decade that are casually discoverable from google. AFAIK, anyone who implies they aren't aware of the biases of editors, are either willfully ignorant (since this is covered under multiple topics within wikipedia itself) or trolling.
