1.d4 refuted...?

there are whole books written about 1.d4 c5. this alone puts the rigorous claim that 1....c5 would be a 'mistake', in doubt.
Hardly. I take no position on 1.d4 c5, whether it's good, bad, ugly, refuted, or sound. But whole books being written about something in chess reflects absolutely nothing about the topic. It just means someone needed a payday.
Yep. I didn't need to search a source very far : http://www.amazon.com/Challenging-Sicilian-With-Repertoire-Books/dp/9548782375
