Counterpoint: even if you want to defend a "middle" position, that doesn't mean every argument roughly in that area is worthy defending. I didn't read the memo, so I have no opinion its merits on their own, but considering the immediate response it had, I'd argue it's not worth defending, because it clearly wasn't written in a way that could ever have a hope of convincing anyone not already on the fence.
>but considering the immediate response it had, I'd argue it's not worth defending That is only a valid stance assuming immediate responses are rational. When anything gets anywhere near a topic like this, the immediate responses that are shouted out will almost never be rational.
