I Pity The Vegan.

Cave men didn't have a real strong source of calcium short of eating the actual bones of their kills.
Given they had such short lives, they really didn't need it as much. The not cutting out dairy products was more directed towards today's people that live 100+ years regularly.

If dairy is your source of bone mineral density, kill yourself.

Wow I didnt know you were going to become so angry and hateful over a topic like this...

Obviously, I didnt intend to say that the only reason to consume dairy products is calcuim, I didnt intend to say that is the sole source of calcium, either.
Obviously, there are other sources of calcium in our diets, but there are a lot of things we get from dairy products that are very useful and beneficial to our bodies. (and again, even those vitamins and/or minerals can be found elsewhere too, Im talking as an option.)

Where is your primary source?
