Stand your ground. Changing your beliefs, pretending theirs is true or attending the meetings for the sake of those that treat you cruelly because someone else told them to shun you is not a good enough reason.
I'm actually quite glad to be rid of these people, now that some time has passed. ( 2.5 years since exit, DF'd since Sept 10th this year )
