Sometimes people just need time to get used to ideas that are strange to them. I believe the community made a mistake by not continuing to include the couple. How else will they have their perceptions challenged than by interacting with the gays at other neighbors houses? Telling someone they are wrong and punishing them by ostraization is failure, Where now is the opportunity to really see a new way of thinking,
I always thought good manners was about making people feel welcome even when they make a faux pas and remembering no matter how rude someone is, the important thing is how you behave yourself.
Seems to me this is more about the gays not being strong enough suffer a little hurt feelings while the new couple gets used to new ideas.
