I think as low of him as you could a human being (ok aside from maybe rapists)
And having him as ufc president showcasing himself all the time on everything is an embarrassment for any ufc fan...
It honestly hinders my enjoyment of the product
He's the president, but he's clearly fulfilling a PR/promoter role.
Dana is more like a Don King character than, say, the president of a bank or whatever. He's the executive face of the organisation - and I think it's better to have someone like him answering press questions than a PR nobody who's 8 levels below executive.
