If the ETS forums are seen primarily as a community where the members need and want to broaden conversations to suit their mood... then leave it be.
If the ETS forums are seen primarily as a place to educate, then by default they take a "stand" on issues... in this case close it down if needed to curtail unwanted discussions.
Is that the question? Or is it more a matter of deciding what topics we educate and stand on? I get the impression that Doug himself was originally only focussed on short-term incidents such as surviving light-plane crashes until rescue. Dealing with 3-month power cuts could be seen as off-topic even if it doesn't attract political discussion.
Personally I'd rather it was on-topic. The discussions have value.
