False; there were several vegan communities long before Watson was even born. As early as 1834, there were vegan communities, they were simply not called vegan yet; just vegetarian or strict vegetarian. Watson coined the word, but he did not invent it.

The vegan society is not the definitive authority on veganism. George Rodger, the current chair of the organization, is not the leader of veganism. He is not the vegan version of the pope. Their magazine, 'The Vegan', is not the vegan version of the bible. It's not organized like that, and the Vegan Society has no such authority as to dictate 'the' vegan doctrine.
I don't know the exact positions of the vegan society, but undoubtedly there will be many things I disagree with them on. If they deem the consumption of oysters unethical, that would be one disagreement right there. That does not make me less of a vegan.

There are organizational structures to vegan
organizations, not to veganism itself. These organizations are separate from each other, and free to disagree. It's like saying there's an organizational structure to charity. There are many charities with organization structures, but not one overarching charity that defines rules and doctrines for all charities to follow.

Exactly; there are many vegan groups. And they disagree with each other all the time, because there is no central authority or doctrine.

My choice of words was perhaps not ideal. What I meant to say is that the question you pose in your original post implies that there is such a thing as
the vegan position, which is plainly wrong. Answering the question, therefore, doesn't make much sense. I can only answer why
individual vegans and vegan groups oppose the consumption of shellfish, not why
veganism does. Because veganism
doesn't do have a position; it's not an agent.
user_id wrote:but if that is the answer than that is pathetic. An ethical theory shouldn't be determined what is easier to say.
I agree. But nonetheless, it might explain why many if not most vegans hold the position that consuming bivalves is unethical. It's just a thought, and it might very well not be the case.
user_id wrote:So then what is the ethical basis for veganism and how does it make sense of the avoidance of shellfish?
The ethical basis for veganism varies between vegans, depending on what kind of normative ethics they subscribe to. The easiest distinction to make is between deontology and consequentialism. Deontological vegans are more likely to believe the consumption of shellfish is unethical, because they think shellfish, being animals, have certain inalienable rights, such as the right not to be used. Consequentialist vegans might believe shellfish are sentient and therefore avoid them. Or they could be unsure whether or not shellfish are sentient, and decide to not take the risk.
My motivation to avoid bivalves is not an ethical one. I avoid them because a) I believe they are unhealthy b) I think they are gross. I am unsure about whether or not non-bivalve shellfish are sentient, and don't bother investigating it because I would not consume them either way for the same reasons as why I don't consume bivalves.
