I've only attended about 25 alanon meetings (which were in about 4 different locations) however I think from what I've seen that the alanon people are judgmental when they bring up the A's in their lives.
It is my experience that many have brought up the A's in their lives and the A's behaviors, and talked about how these behaviors affected them.
I have heard from others that the behaviors of the A's in their lives were not brought up at their alanon meetings.
Different experiences at different places...I'm sure this is also true of AA meetings.
So yes, if you mention you are an A, you might be judged by some others, probably new people who are really hurting at the time. Maybe you don't mention you are a double winner until the people there accept you as an alanon person first? Later, once accepted into the group, you could reveal that too.
