I already linked to this once, but it’s worthy of re-reading. It applies to all groups I know of.
It’s not perfect. But one thing I keep reminding myself is that we are an amazing mish-mash of people. We are not homogeneous. We don’t even have our definable culture. Like a big family at Thanksgiving, there will be disagreement. There might even be some mashed potato on the wall at the end of the evening, but we are family.
