How does one become "clean"?
They repent earnestly and mean it in their heart that they will strvie to stop using naughty words.
Which was the case of this person I have no clue what else one does only where in this case where there is smoke their is fire!
and when ever this kind of stuff is talked about those who dislike the LDS try to find a loop hole and go off in another direction instead of seeing the action.
this tells me how much one really holds in their heart the repect for the Lord counsel when so many always wants to throw it back on the obsever
