I have met several true vegetarians, but then they also fall into several groups, those that eat eggs and dairy products, those that eat eggs but not dairy and vice versa, and those who eat no eggs or dairy products, besides not eating any meat, fish, fowl, or animal such as cow, pig, etc.
I have only known one true JW vegetarian and they gave it up after 5 years saying it was too time-consuming. I'm sure it put a crimp in their social life.
I have heard it both ways from JWs in regard to the time after Armageddon:
1) That there will be no hunting or fishing or eating of any animals.
2) That there will be hunting and fishing and that they will still be enjoying a big, juicy steak (and these were elders).
I have tried to research what the WTS has said on this and it seems to be that the official position is that animals will not be killed and eaten in "the new system"TM Note that every picture in the WT publications of people eating after Armagedoon shows only fruit, vegetables, nuts, not even cheese or eggs.
I would have found that a wonderful opportunity to point out to these pseudo vegetarians that they should not be eating meat then. But then if most of us had to kill and clean the meat we eat, we might become vegetarians.
