One can replace a word 'human flesh' in the place of non-vegetarian.

Imagination can be used anywhere. The biological as well as common man's view suggest that the flesh of animals are more similar than anything else. If beef is the flesh from cow, then human flesh can also be eatable. Go and eat some and then talk about the goodness of non-vegetarianism.

We can think in anyway. Animals are animals and should behave like they are. And never will say 'rational'. Only some humans says they are ahead of them all. Its so poor and pathetic that beings are here in the natural world and using language as their tools to dominate. The day surely will come and all will recognise at that time only that, beings are mere part of this universe - soon or later.

Me not against killing or something else. But one should not take control over the nature as it is above our capacities. The Cow, goat, pig, rabbit or any animal should not be used for a business purpose. Just because, when a day come our next generation definitely will use fellow humans for their business purposes. It is already in the business as well. Organ selling and blood business etc. were the aftershocks now a days. If one can take these examples into strong points, never do it on any natural thing. Beware of the future. All of them were going to struggle in the next coming days.

Killing is not good for living at all.
