Hmm, I guess in my mind it comes down to a question of the "vision" of these forums.

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.

Personally, I see ETS as more of a place that educates, passes (appropriate) judgements, and takes a stand on issues. And I think that's a good thing.

Finally, I worry that with all of the uncertainty and fear out there right now, that even people exercising "healthy" discussions here can add to the overall crush of negativity. Not intenionally, but by joining the bandwagon it's an unintended consequence. Perhaps a sharp refocusing right now is not a bad thing...
