Humble suggestion: Instead of complaining, you could be constructive, posting an opposing point of view with appropriate support, as most of the other dissenters have done.
(Perhaps "[citation needed]" came across as snarky? Next time I'll write "What's your evidence?".)
The rest of my posts weren't complaining, either; mainly, I was arguing for the importance of getting people to do 1 and 2 above, and against the notion that it wouldn't be better for opinions (of the "claims you believe to be true" variety, not preferences) to be either supported or marked as hypotheses when they are expressed (at least in this sort of context).
I was definitely not dissenting; my criticism would be exactly the same even if I agreed with the expressed claims 100%.
