It's not obvious what people do you should argue. The pattern to study some technical stuff, and questions specialists, work for settled science not for unusual topics that pop up here.

I am not including Less Wrong whose dynamic is completely different

For some LWers, the LessWrong community is far more critical than others. If you think the same, then say why. Some forums float around topics with the disagreement is more frequent, for bad reasons. Others not.
