Tom Brown claimed (I'm not sure of it's validity, but let's say it's true) that he walked into a forest one day with nothing but clothes on and a Knife and walked out several years later feeling fine. THAT is minimalism.

Anyway, I don't think that this commenter is 'angry', he just doesn't feel like what your doing is really all that minimalist because you don't kill/grow your own food. Of course I'm not really sure I agree with him. You are minimalist in some ways and not others. I don't really see what's wrong with that.
