Don't you think that "ideological reasons" can be quite a good reason to do things?

Besides, following ideological reasons only means to value certain (other) aspects higher for evaluating the question how good something is.

Usually the term ideological implies (in my book) that a person is considering the greater good, and willing to take a step back in own convenience. That sounds like a nice person to me. Maybe you could spare some curiosity for their reasons?

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).
