There are all sorts of legitimate reasons (nutritional, spiritual, moral, technological) to direct nutritional choices, like eating or not eating meat. What does it have to do with "depriving oneself"? That's not a common reason to stop eating meat.

I'm referring to those people who, in the name of caring for "environment", are wont to do things like depriving themselves, and attempting to deprive others[1], of the pleasure of eating meat and yet has no hesitation whatsover in using their car for daily commute, spending a forture on fashion, etc.
