Mediation? You don't think this has gone that far, do you? This is just another exchange that has remained calm for the most part. I can't speak for DtWB but I'm not taking this personally. The only time where I really felt he crossed the line was when he brought my mom into this. I mean, that's just wrong.
I'll never cower to anyone who wants to make things personal, but if it seems that it's just gone too far, then I'm cool with dropping it right here. I think I've said enough on the matter anyways, and I have no problem letting things lie where they are.
