This is pretty much how I feel a lot of the time.
And if vegetarians want to be sanctimonious about something then they should look at the damage soy and quinoa production are causing right now to all those poor folks that you feel you are supporting when you buy Fair Trade. All to feed a dietary obsession, and yes for some,it is an obsession. Obsession with what they are eating, and what everyone else is eating and an almost evangelical need to convert as many folk as possible.
Why this need to justify yourself? No one cares what you put in your mouth, and actually if you are so into “freedom of choice” then just shut it and let the rest of us eat what we like in peace.
