Is it wrong to call a boy a girl?

There is much fuss at the minute about name calling. I certainly agree that calling people names in an attempt to demean them is an unpleasant act, and one that should be discouraged. But in recent debate I have noticed that people are getting very upset about statements such as "you throw like a girl" etc. The implication is that this is demeaning to girls. I wish to argue that until recently, that has not been true.

The problem is power, and our failure to learn

A couple of years back a Vietnamese colleague of mine told me how his father had to flee from Vietnam (after the war I believe). I asked about his family, and apart from his father, who was an academic, the rest were all farmers. Curious about how bad things really were in Vietnam before the war, and in so-called 'poor developing nations' in general, I enquired about the standard of living of his farming relatives, in particular his uncle - whom we were discussing.
