Genuine or not, AC is not lying. I can think of one very recent example in our hall where a sister openly and publicly did not invite some kids of a single parent family to join in with an event she organised because the parent is not 100% regular at all the meetings. She saw no problem with it even though all the other kids in the cong were invited. What's worse, she was a single parent herself.
Hypocrite.
The comments on having to pass muster with judgmental cliques is spot on as well.
