Reply #111: Then address it as such.

If you feel offended, address the issue in a clear manner.
Were JonQ's comments polite? I don't think they were, but replying that he should stop abusing alcohol isn't the right way to resolve the situation. If you take issue with his post, say so and/or report him. Both of those options would be appropriate, as to the terms of DU discussions. Telling him to lay off the booze...not so much.

I made no lies. You made a personal attack. I pointed that out.
