when i was growing up, the creed of folks who would segregate those who had the audacity to reject their place was, birds of a feather flock together.
i wouldn't think much about it except i overheard someone say it just the other day.
it is a tough observation of nature to argue otherwise.
but if you watch birds, you notice that there are a lot of different kinds, more like an infinity different kinds, which gets me wondering that some birds must be flocking somewhere with birds of a different feather.
and any self-respecting bird watcher worth his or her salt would tell you, thank god they do, or it would be a pretty sad state of affairs for their hobby.
so it might be best for folks who want to legitimize their prejudice and bigotry to steer clear of natural observations, since this all appears to be pretty much a human endeavor.
