We’ve had some discussions about civility lately. This is also about having a productive discussion as well, I think.

Comments like the above don’t meaningfully contribute to the discussion, and while they call “results” “objectively stupid” and not people, they tend to raise the temperature of a discussion in such a way that the latter seems only a few more flamewar posts away. I know people have deeply held opinions on things, but simply calling things “objectively stupid” repeatedly and loudly isn’t going to change any of those opinions.

We know it won’t do that, because it hasn’t done that for the last two (?) years already. What we know it does, after experiencing it for the past two-ish years, is just make everyone sick of the mailinglists and increasingly testy towards one another, which is an outcome I think nobody wants.

Can we stop with this, please?
