I saw it: it's a shame for him to try to throw diabetics under the bus like that, but I doubt anyone is going to believe him. He tried 'diabetes made me do it' then 'I'm a member of a Baptist Church so I can't be racist', and then of course 'I've got kids'. It was all quite undignified to be honest. Etan Thomas had quite a good quotation on it:
"Did it surprise me? Not at all. It was, however, shocking to hear Rowan blame his comments on his “spiking sugar levels” in his official statement. I wasn’t aware that racism was a side effect of diabetes."
