I think making the topic in Politics & Elections was a mistake, that category is more about the horse race and less about grand philosophy. fortyv seemed to want a philosophical debate at the outset. Hence the open ended prompt and the tedious definition of terms - standard practice for philosophical debates I have attended in real life. And for conversing with bored philosophers in general.
But it was Politics & Elections, so at every turn, the Teeming Millions expected him to make a specific and detailed proposal. That way, they could evaluate the political feasibility.
That must have been a little frustrating if he wasn’t familiar with this place. It doesn’t go so far as to excuse the tone adopted in post #25, etc. Assuming he started in good faith, he quickly lost his head, and if he had not yet resorted to trolling, he was very close to it. That seems to be what got him banned.
On the other hand, even in Great Debates this kind of open-ended debate would not fit with the new rules. He would have had to spin off a new topic for every tangent, and there are a lot of tangents involved if you’re trying to design a practical utopia.
