I already warned about “drooling idiocy”. As for “simplistic, ignorant and ill-informed stereotypes you hold”, well, then if someone thinks all blacks are rapists we can’t call their sterotype simplistic? If someone thinks all dinosaur bones are a hoax we can’t say they are ignorant? If someone thinks France is a state in the country of Europe we can’t call them ill-informed? While my ideal would be more polite debate, I don’t feel I can get in a tizzy about comments made by one poster that would be acceptable if made by another.
If Sparc refers to “their hateful little regurgitations of lies, half-truths, misinterpretations and idiocy” about the white nationalist posts can C be banned for “drooling idiocy”?
If Scylla refers to another posters’ “idiotic opinions” can C be banned for “drooling idiocy”?
If Gex Gex says “Fundamentalism is synonymous with idiocy” can C be banned for “drooling idiocy”?
If Abe says to another poster “you keep posting here as if this forum were your own lavatory […] I mean explain it with valid arguments, not the political idiocy you have posted” can C be banned for “drooling idiocy”?
And all these examples are from the last few months. The fact is, if you want the right to say to the latest twit who argues that, oh, Republicans or Jews or Gay or blacks are perverted, mentally deficient child molestors, “That’s idiotic!”… that gives Collunsbusy the right to say a post is idiotic too. And even if you don’t want that right, the fact remains that we GD mods think the right to call a bullshit argument a bullshit argument or a stupid point a stupid point or an idiotic remark an idiotic remark is worthwhile enough that it’s worth putting up with people using it when it’s really not appropriate in our eyes.
With enough people around, no matter where you draw the line someone is going to be reallllly close to it. And if I move the line someone else will be reallllly close. GD is a forum where people come to argue and tempers run high, and there is no “you must be polite” rule else half the forum’d be banned, and probably a Mod or two. 
However, this doesn’t mean that I think Collunsbury has a free ride to keep posting in the “drooling idiocy” vein I already warned for. Clearly, I do not quite think he should be banned right this instant, but that may change in the future.
