The point of debate is to have honest discussion. It's much more interesting to debate reality rather than blatant lies or false information. Don't you agree? Shouldn't that be the starting spot? I am calling you out on peddling misinformation. If you are stating misinformation intentionally you are lying and if you are stating misinformation because you are ill-informed then you are ignorant (without knowledge). It's not "petty name calling" but rather an observation, as I have stated several times.
Perhaps you have an "alternative" word for passing along false information that would not trigger you as much that you would like me to use instead of lying or ignorant?
