A few weeks ago, My wife and I were in the parking lot of a local grocery store. A CD walked past our car and my wife about had a fit. This CD did not even try to pass which is ok with me. She was very obvious with no wig, long hair and balding head with no make-up except lipstick. My wife asked me where we were and said she would expect this in San Francisco but not in a small town. My wife then said she had a real problem with this CD. I guess I will be in the closet with my wife forever.
This sounds like the perfect opportunity to open a dialogue and discuss her ill-informed prejudices. If my SO made a comment that I thought was narrow-minded I would at least challenge it and talk about it.

If your SO had made a racist comment would you have let it go unchallenged? Would you not have questioned her and tried understand why she held such views?
