are vegetarians more ethical by not eating meat?

[Something completely different]

I think an Atheist (naturalist) should not eat at all....................... or be a Cannibal
Yes

all species are cannibals you savage idiot.
there are active and passive cannibals, the passive one only eats members of his own species when confronted with no other food, the active one actively hunts conspecific animals.

If you eat meat or even plants you will be eating your relatives
because according to "Evolution theory" there is no species; all are coming from a single source so they are related,

some biology for the halfwit:

a species is defined as a group of organisms capable of interbreeding and producing fertile offspring

One can easily say that all living things are releated, yet to jump to the conclusion that this therefor makes everyone cannibals is like saying that

"Britains must always have offspring with people from outside of britain or else the country would fill up with inbreeds"

Cannibalism is eating someone from the same species - I cannot interbreed with a pig. the posibility of interbreeding is what categorises species. So a pig is not from my species.

When you try to eat your niece (a Chicken) think again and save her life hock:

A chicken cannot interbreed with a human and therefor is from a different species.

On the other hand, if you allow yourself to eat other (relatives)
Why don't you eat humans as well
there is no difference a chicken is the same as a chic

I explained to you how species are categorised.

Now you should learn biology for yourself, idealy in a school, because I am neighter your teacher or mum nore a caretake for retards like you.
