Stacy-Marie hits the nail on the head (i.e., gets the point correct) in her paraphrasing of the wiki definition of "sissy":
Think this through people, the man who addressed Dana intended to give offense and the most likely interpretation of his behavior has nothing to do with sub-genres of crossdressing.
He likely cares very little about whether some men like to be maids, instead reacting to both his fear of emasculation by association with effeminate males and his deep seated misogyny. There are a great many social science studies linking homophobia to misogyny and it makes perfect sense. (Do some digging, you might be surprised at what you find.)
Remember, whatever label you give yourself, crossdressers "transgress" established gender norms in most societies (particularly rural parts of "modern" western societies). This is one reason why the notion of "transgender" as a broad label (covering crossdressing, transexuals, etc) is so compelling because it has the literary implication of "transgression".
Many men (in the U.S. anyway) feel that a man who transgresses his accepted gender roles is a threat to other men in a very personal way.
While I realize that much of the invective on this thread was written either as black humor (which I enjoy) or as catharsis, I must urge you not to respond to this idiot with any kind of violence. This solves nothing and may get you killed.
I am not being reactionary, I am being sensible. If you confront him, you make the threat real and you may find yourself severely beaten, or worse.
Engage people like this very cautiously. Violence against trans people is a huge problem and not to be taken lightly.
