That is messy, I grant you. Let me give you another example of a mess.
Ontario is about to have an election. We don't know who will wind up being the new government. We could imagine a very tidy election scenario, like, say the People's Republic of China or the people's democratic republic of North Korea, where we'll know exactly who is going to win beforehand. I'm just saying that untidiness is sort of inherent in democracy.
I want to submit to you, as a counter-proposition, the idea that norms grow culturally in a messy way, but they do emerge. As to what is a reasonable set of debates, what kinds of topics they ought be on, whether there should be specialized topic debates, what the ratio of English and French languages ought to be, length of interventions and so on.... I would submit it's better to have them emerge organically and be generally accepted in society. If it's felt that it's too restrictive, there will be pressure on someone to create a new debate beyond the ones that already exist. It actually did happen in the last election.
Does that not seem like a robust solution that we really haven't given a great chance to develop, given the fact that last time around we could see some new formatting springing up that had never previously happened?
