And what I'd like is for those promoting the woo to not display their contempt - by ignoring, or trying circumvent, the conventions of science - in the first place.
But I doubt that'll happen.
When someone talks b*llocks there should not only be no surprise when the response is open sarcasm or whatever but also no condemnation of those doing so.
Or perhaps you'd manage to be politely credulous if someone walked up to you in real life and claimed that they actually had 3 hands and were 27 feet tall.
Assertions with no evidence that contradict known facts (or invent their own "facts") deserve zero respect and those promoting them deserve none either.
Unless you're positing that such posters are mentally ill and should be treated as if they weren't rational socially-adjusted adults (i.e. they don't fall under any "normal" rules of personal interaction).
