Of course.
Whenever one relates personal experience in a public fora, esp. one with pretentions of logical thinking, the default reaction's to relegate it to an anecdote. The self reported intellectuals cry: "It's an anecdote so it doesn't count!"
Ok.
But I'm not writing a paper. I'm merely relating my experiences and subsequent thoughts. Surely many black people went through the same experience when talking about their "anomalous" and "anecdotal" interactions.
Having a cop threaten me with a gun because I had the effrontery to claim a headache is an anecdote. But, it's one that indubitably influences how I approach subsequent interactions and -- moreover -- my whole stance on exactly how the power-balance in any citizen-to-cop interaction works.
Yeah, plural of anecdote isn't data, but I'm not waiting for a scientific paper before I start forming my own opinions of the world.
