I can't really see why debating shouldn't be a part of the Member's Lounge. Sure, some people are CLEARLY overreacting, but that's what we mods are there for anyway, and aside from these isolate cases, I, for one, tend to think of debating Topics as "laid back" ones where I can have some fun, and perhaps learn a few things, so I think it fits perfectly with the Member's Lounge's goal.
So, if you guys want yet another Forum for debating, well, who am I to say anything? But I really don't see the point. Also, "mock" debates would fit the Member's Lounge even better than an actual Debating Forum, so, yet again, I think it's not necessary for we to have one.
