I am a semi vegetarian meaning I am mostly vegetarian except when my family is here. I was a vegetarian for 10 years at one time. I couldn't be a vegan because I eat my eggs. Also, have Celiacs so no wheat and no meat make t difficult to eat in some places. Eliminating dairy would be a real burden on top of the other two.
No offense, but it is kind of a real burden on the cows.
