Lisa:  

Hmmm indeed.  Here it is from JKR's own site:

Why are some people in the wizarding world (e.g., Harry) called 'half-
blood' even though both their parents were magical?
The expressions 'pure-blood', 'half-blood' and 'Muggle-born' have 
been coined by people to whom these distinctions matter, and express 
their originators' prejudices. As far as somebody like Lucius Malfoy 
is concerned, for instance, a Muggle-born is as 'bad' as a Muggle. 
Therefore Harry would be considered only 'half' wizard, because of 
his mother's grandparents.

If you think this is far-fetched, look at some of the real charts the 
Nazis used to show what constituted 'Aryan' or 'Jewish' blood. I saw 
one in the Holocaust Museum in Washington when I had already devised 
the 'pure-blood', 'half-blood' and 'Muggle-born' definitions, and was 
chilled to see that the Nazis used precisely the same warped logic as 
the Death Eaters. A single Jewish grandparent 'polluted' the blood, 
according to their propaganda.

So there you go.
