My Craigslist post said, among other things, “I’m a 36-year-old white guy. I grew up in a diverse neighborhood and have always gone to diverse schools. I’ve always had a decent number of black friends. That’s changed over time. I work in the publishing industry, which is super white, and I’ve realized that my group of friends is getting whiter and whiter.… It’s amazing to me that almost everyone I know has either black friends or white friends, but not both. We could have a black president, and still not have a very mixed country.” Then I added a few more lines about don’t let me show up at the bar and you’ve got a horse tranquilizer for my drink. I guess you could say the post ran a little long. I guess you could say I was worried about the possibility of a misunderstanding.
