The thing is, all of your thoughts and feelings about the organization are irrelevant. Her life, her sobriety, her choice. It would be the same as someone telling me I can't run because they believe it's bad for knees and why don't I try a stationary bike instead? Um, because I like to run and lift and if you support me being fit, then running and lifting is what you support. Since that's what I do.
You don't get to choose HOW to support her sobriety and growth, she does. Your choice is to either support it by being supportive or not. In which case don't pretend you do support her - you don't.
