Personally, I think that if those that are "thin skinned" and take things too seriously can "lighten up", those that are the most strident nit-pickers and complainers can just as easily either back off or hold their tongues (uh, keyboards). We're not all insiders to the core bunch and those that are could take that into consideration. Whether it is meant in good fun or not, it often doesn't sound that way and it gets really tiresome.
