I understand your reaction...but I think you sounded like you were trying to fit in with the drunks and your comment was ill taken and she reacted strongly...maybe she and hubby have discussed their own drinking issues at length...and the fact that you have stopped....sometimes people perceive others behavior as a threat....maybe your sobriety is threatening to her because she can't stop...it's difficult to get inside her head and why would you waste your time?
Real friends support you and you do activities you all enjoy...the activity here sounds like it was just the booze...what fun is that? to watch others doing shots? you have better things to do with your time than watch others get poop-faced...you are not going to find intelligent interaction with these people pouring shots for eachother.
I hope you find some new more interesting people to hang with.
