I'm not sure how alone I am in this because no other dissenting voices spoke up at all.

Can we encourage people to speak up if they are in informed disagreement with consensus, and trust the rationalist community to call them out if they are wrong?

There's no harm in having a minority opinion or getting called out for being incorrect, but we definitely want to hear about arguments that might make us change our minds, or a valuable additional data point of an observer's assessment of the evidence.

As long as we don't hesitate to justify the consensus, it seems like more dissent is good, not bad.
