Sounds to me like she was already aware of it, had had other complaints. And the idea that she needed lauraelmore to identify them for her ... if it's anything like the groups I've known, you don't have to have Spidey Sense to pick them out. Sounds like the owner would rather keep this core group of paying customers, than make anyone else welcome in her studio.
I'm with PamNY. It makes me really sad and angry that you were forced out of this studio that you'd been benefiting from, but it's not your job to fix it.
I really would encourage you to try to find another studio though, maybe after a break. I'll do videos at home when there's no good alternative, but I don't see it as a long term thing. Personal instruction is important for anyone, even masters of their sport or other discipline, and social interaction CAN be good too, there really are places without all that drama.
