For as long as I can remember CDers have been singled out for criticism. For example, if you're trying to say something insulting about someone, "he probably wears ladies underwear" will always work.
When you come out of the closet you are so vulnerable. You are immediately open for criticism and possibly osctracism. It doesn't help that the are reasons for cd'ing are misunderstood and for the most part a mystery to ourselves and others .
My wife has known about my cd'ing for over ten years. She is for the most part okay with it, but there are still times when she's a little put off by it.
