Ideology is all fine and well until you start to deviate too much from reality. Then you hit a wall.

Example : there are cases of babies dying because their parents refused to give them animal milk.

Be pragmatic : you don't want to hurt animals, OK, but why not raising a couple chicken to get some eggs ?

Fwiw, my servers are Linux, but my desktop is Windows (it's not for lack of trying Linux as a desktop).
