Comment: If you "know" the comment to be uncivil, then why the *&^% are you asking us to vote on it? Furthermore, I vote no 100% of the time which produces a moronic spam notice stating I am excluded from voting though I am still forced to vote, and at no time am I restricted to 3 posts a day. Your bigotry towards Motley, whom at times I loathe, is despicable, but is well expected from the RG that habitually is an effin embarrassment to professional journalism.

Ex Output:
Non-identity-attack
