Some problems that NVC tries to solve 
can be solved by a clean cut much faster. 😎
At the Yoga ashram I had my fair share of experiences, how one disturbed person can spoil it for the rest of a group/team.
And sometimes them crazies have so much power/ energy, maybe a case of Kundalini directed wrongly, that the only way to dissolve the situation, and also to protect other people from them, is to expel them.
One of my rules in dealing with people has always been:
"One cannot allow the unwell people to make the healthy people also unwell."
So you made the clean cut, congratulations!
