Because it's a false dischotomy to say that to criticize Mixon's report is to support Sriduangkaew. To take a deliberately ridiculous example for the sake of the point, if Mixon had published her report on the heartwood of a five-hundred-year-old redwood, no-one would think it was supporting Sriduangkaew to say, "Uh, thanks for the report, but maybe you didn't have to cut down that tree to do it?" Everything else is disagreement about the degree.
