It's your board De. You have more patience and apparently a deaf ear to the obscene, offensive language that spews forth from this individual as normal language ..
I can no longer tolerate it and do not want it to permeate through my eyes and inside of me.
I understand your objective. I would tell that reprobate in no uncertain terms to clean his mouth up or he would be toast, quickly.
As far as civilized discussion, I have no problem with that. He is there to only disrupt and curse, swear, say obscene things, and enjoy doing so.
There has not been one single coherent intelligible thing written from him..
But, all that said, it is YOUR board and decision to make. I agree that I do not have to read it or it.
No problem here....
