Sure not! And why should Anybody? There are enough comments made on this point. Reading all of them concludes: It goes both ways. Some vegetarians looks down upon meat-eaters. Same way some meat-eaters looks down upon vegetarians. It does not make any sense. Why? I personally believe that "You are what you eat", just like the fact that you always wish that your child should become a successful in their life. So you want to provide them whatever best you can. We try our best to take care of them. Again everybody have their own definition of what is good. What I think is good may be very bad for others. One thing I am sure on this: My mind and body can be affected by what I feed in, what way I feed in and with what attitude I feed in. I think that my body is a very precious gift from the God and I should make a good use of it with a first step by putting in whatever good is available in a right amount, manner and with respect.
Scientifically it has already proven by Newton's third law: Every action has an equal (and opposite) reaction. Now again, it does not have to be proved by any scientist. It is Almighty's law. It is nature's law. Should not we treat everybody with a great respect regardless of their age, race, knowledge or material success? If not then why should we expect to be treated with any respect? There is no action which is ONE-WAY.
When somebody can not be agree with me, I hardly get upset. Everybody reacts according to the way they grew up or raised or taught.
You just can not control anybody but you and your actions.
These are just my thoughts, I may be wrong. I do not intend to upset anybody.
