Maybe suggest that the group ask that cross talk be avoided when opening the meeting. I used to hate others interjecting when someone else was sharing but now I attend a meeting where this is done a lot and actually enjoy it. I think it depends on how well everyone knows each other and the level of trust and intimacy between group members.
I have also learned to not take things so personally at meetings. Believe me, as an open agnostic I get my share of cold shoulders in AA. But there's many more nice people than judgmental I have found.
