When we're discussing controversial issues, the bar for civility and substantiveness goes up because the kindling is particularly dry and we don't want a flamewar. So we need commenters to bring their opinions clearly and carefully—we need more than "Yeah, good luck with that." If you believe something to be well-founded, please share its well-foundedness with us! That's what we're here for.
