The history of Vegetarianism  started in ancient India and ancient Greece.
Really? So Indians and Greeks were the first vegetarians on the planet 
Yes it seems so... Not only ancient India and Greece, but also civilizations in southern Italy.
Ok. I don't really like been a vegetarian because I love to eat meat and fish 
I don't care about red meat, I could live without it.  But I need my chicken and turkey! In the Christianize new world of the Roman Empire during 4-6th centuries vegans almost disappeared. 
Vegetarians have a substitute for meat. They call it chunks  
I like tofu so I could handle that. Vegetarianism voluntary non-consumption of the flesh of any animal 
I have tasted vegetarian chunks. It tastes good and made from soya beans but I cannot do without meat 
I like the idea of the idea of nonviolence toward animals.
That is true but some people become vegetarians because of health reasons
