No. When he is questioned about the statistics, in which case he'd likely defend their validity because it's essential to his argument; that is when he's faced with the burden of proof. But not before that.
The first part puts the onus on the original poster, and the second on the commentor. The statistics could be completely false with no actual substance AND racist (whatever that would mean), or they could be substantiated by recorded information AND racist; also, it could be considered not racist at all. So the original poster would need to show why they are believable or valid, but would not need to answer whether it is racist or not.
