Dancer bothers me for a number of reasons. He doesn't spell out how conditions were much different when he originally succeeded. He doesn't spell out all of his unstated backers way back when that allowed him to do things beyond his bankroll. He doesn't explain that without his current statuses (and possible rebates) that what he does can't be duplicated from scratch today. Or duplicated at all. He never addresses addiction directly. His articles imply that he dabbles into areas of gambling where he has no expertise (such as sports betting), but he presents himself as being able to judge whether he knows what he's doing.
Those are solid reasons to criticize him outside of his personal life and weirdly sexist writing.
