@Kevinjohn Gallagher - Yo.

If the community wants "diversity", "openness", "acceptance" and the list could go on at length, the thin-skinned, tender and gratuitously politically correct will have to don their armor or toughen-up.

To move beyond the clique and the lounge-lizards, to make room for the greenhorns and whoevers, unavoidably means hosting specimens who are not smooth, oiled, honed, etc.

It is not practical to educate & train such people in the manners you would rather see them express, and especially not as a precondition of entry or participation.

There are the knowingly ornery, pugnacious, and congenitally Scottish. It's legal, and in America their lip is protected under The First. Besides, they usually are in fact better than you, and right. Then there is a broad spectrum of crude types with relatively low awareness of their inappropriateness and a lack of skill or willingness to address or even acknowledge their deficiencies.

You wanna open it up? I applaud ... but brace yourselves.
