From my experience of 33 years in the Borg as a convert in more than 6 congregations ,I didnt observe anyone striving to put on a new Personality Looking back on it now ,I dont think anybody took that scripture seriously .
As a group of people they were no different from any other worldly class of people with their own idiosyncrasys,judgemental ,self righteous sometimes arrogant ,know it all,obnoxious behaviour .
Of course not everybody was like me.their were a few and I emphasize "few" who were genuinely nice helpful people.They were a rarity.
