Certainly, there are more instances of chapters without advisors than there should be, but I still don't understand fighting so hard to remain a part of something where you're not wanted.

If this had happened to me, I probably would have resigned long ago. There's always girl drama in chapters whether advisors are around or not, but in the scenario described by the OP, I'd be running as fast as I could away from all that. I also hate drama and would prefer to be alone than to be around it, but certainly YMMV.

ETA: It would seem to me that an advisor-less chapter would be less likely to call members into standards than one with an advisor. It has been my experience that most active members would rather ignore issues than to confront them directly. Much of my time as an advisor has been spent telling my advisees that they HAVE to deal with X situation.
