If it were me that this had happened to I'd .... Not really. I wouldn't know how I would react. Just so sorry you had this happen.
Sometimes it just seems someone is having a really bad day or life and lets it show in inappropriate ways.
Maybe you could tell a few of your Wed group friends what happened and how you felt. Then ask them to back me up with good Christian comments and prayer. It may be that your presence and prayers will help this group become what it should be. If that doesn't work, then only go to Triple F.
When something happens to me like this I try to act like a genteel southern lady wearing my gloves and say something really nice .... Though I do admit it is hard to do. I do best when I already have a squelch ready to my mind.
