The Darwin fish post reminded me of this (details fudged, name invented):
I have a relative who lives far away from me. We aren't particularly close (she's a perfectly nice person, but we have little in common), but since she's an avid user of Facebook, I'm always seeing what she's up to.
However, my jaw dropped when she wrote that she was running around getting ready to host a LGBT party for her teenager. You see, she and her whole family are an active and devout members of a faith that considers homosexuality a sin. She would never publicly say or do anything remotely homophobic, but I am pretty sure that she would not knowingly socialize with g@y people in her own home, nor would she permit her children to do so. She also lives in a community where most residents share her faith. If any of her children are g@y, they would be deeply closeted.
So I was very, very puzzled.
Before asking her or another relative who knows her better, I did a bit of Googling. It turned out to be a end of-the-year party for the Lobo Grande Baton Twirlers.
