You not only have a right and a priviledge to speak up, but a duty to do so when you see something going on that is not right and threatens the well-being of the group.Consult your group's conscience on such matters
It is one thing to be straight forward, even blunt. I come across that way myself and often get accused of being rigid & intolereant. But I draw the line at personal attack.
Guys like this give the term "old-timer" a bad name. There is no such thing as seniority in Alcoholics Anonymous. No one is number one, but no one is mumber two and we all have a voice.
Sounds to me like this guy is a classic example of the old-timer that either hasn't taken the steps or hasn't taken any spiritual action in a long time. When I get rigid it means I'm not growing, in fact something that is rigid is dead. One of the signs of rigidity is legalism, intolerance, a know-it-all-attitude, and a holier-than-thou attitude. When I get this way, it is a sign for me that I need to do some work.
