Active and Passive Vegetarianism

To my knowledge these terms don't exist, if they do then ho hum.  I'd like to coin these terms if they don't and I would like to define them as follows.

An active vegetarian does not eat meat at all, they object to the consumption of meat for whatever grounds they may.

A passive vegetarian does not purchase meat at all, they object to the cultivation of animals for consumption.

The difference here is that a passive vegetarian may consume meat.  Now the reason I think these terms need to exist is basically down to the mentality of the vulture which I have discussed before.  In a nutshell my argument is this:  I accept that you object to the cultivation of animals for consumption but if you are a guest in someone's home or if you are offered meat and you reject it, if that food is not consumed by someone else it will be wasted and wastage of meat to someone who truly objects to the cultivation of animals should be a higher priority than your abstention.

If you are presented meat on a plate that no-one else is going to consume, and you reject it, everything you protest as the grounds against meat consumption becomes senseless as a direct consequence of your rejection.  If you reject the meat of an animal that is already dead and has already been processed then you make that the animal died for nothing.  By rejecting meat on what is essentially a political motivation you are being incredibly selfish.  Rejecting meat in a situation where you were not the person with purchasing power will not make the animal come back to life and it will not result in a reduction of worldwide meat consumption as you weren't the person that bought it and therefore have absolutely no effect on the purchasing habit of whoever did.

A passive vegetarian should abstain from buying meat therefore reducing the amount of money spent buying meat and the amount of meat that is purchased consequently reducing demand.  In situations where you do not have purchasing power your abstention has absolutely no effect on the purchasing habits of the person who did.

An active vegetarian is one that outright rejects meat completely in all situations.  This I see as pointless.  If an animal is already dead, and someone has already bought it and cooked it, whether I eat it or not will have no effect on whether or not more will die - it will however determine whether the food is wasted.  Active vegetarianism is a first world political choice that is incredibly selfish.
