I dunno, it seems pretty common in the debate world to do some sort of stylized thing (it's been happening for decades, really). They do their research and write up their arguments, but the delivery in the actual debate is not the norm, which I think is fine if that's what they want to do. I personally would prefer a standard debate, but I'm pretty indifferent to this. The goal is to win the debate, which they seem to have done. If they provide a strong argument which can't be countered, regardless of the delivery, then they've accomplished what they set out to do.
