White Chocolate is not Chocolate

I've given up chocolate for lent again. I did this a couple of years ago and I'd just about forgotten the torment I went through. So I've done it again.

Fortunately white chocolate (which I am extremely partial to) is not actually chocolate. The chain of reasoning that leads me to this happy conclusion works like this:

White Elephant stalls do not sell elephants. Therefore White Chocolate cannot actually be chocolate.

People have argued with this. They have made the point, forcefully and with passion, that one of the ingredients of white chocolate is "cocoa butter", an ingredient which is also present in real (i.e. non-white) chocolate. I am unmoved by this. Does it mean that butter contains chocolate as well? Of course not. So, let's hear it for the Milky Bar Kid folks.....
