While I too find it odd that your original comment was downmodded (has it been edited?), I don't think that a personal attack is an appropriate response. It doesn't seem like younata was being a jerk (from my reading of the comments), but your response is a bit vitriolic even if he was.

From your comment history, I speculate that you - like me - are a long-time reader and only an occasional poster. These posts stand out as being unusually negative. I'd urge you to strongly consider changing your tone (and perhaps deleting your posts in this thread). Don't let this one altercation drive you away from the community.

Best -- David
