If the only connection to "meat" is the initial stem cell gathering then you may be right that it's not technically vegan but I can't imagine most people would care about that

> I can't imagine most people would care about that

It depends. In India for example, vegetarians also have a learnt aversion towards meat (for religious/caste reasons). Even now, in colleges, many vegetarian students demand to have their own separate hostels and canteens, so that they don't have to use the same utensils that have once been contaminated with meat (even though they have been washed thoroughly with soap after).

For someone like this, anything meat like is disgust-inducing and not even remotely an option.

True. Personally I'd be happy with that myself, but that definitionally makes me a non-vegan

So getting cultured meat from a human who agreed to it is ethical and therefore vegan ?

Vegan doesn't follow from ethical. While this would technically qualify as vegan, most people also have a pretty strong stance against cannibalism even if voluntary.

Implying that because you satisfy the criteria of one moral principal means that all other moral principals are void is nonsense-think.

Of the vegans I know in real life, none take such a hard-line approach with respect to products such as vaccines that were initially cultured with animal tissue, or even tested on animals. [1] I assume cultured meat would fall into a similar category, though they might avoid it for other reasons. When we discussed it, most of them also do not object to native peoples hunting wild animals or judge people who consume animal products in places (e.g. above the arctic circle) where a vegan diet is cost-prohibitive.

There are no doubt vegan purists who consider my friends to be "bad vegans", I'm just bringing it up to refute the notion that the vegan community is as fanatical or monolithic as some make them out to be.

India has banned production of cheese using rennet, which is why quality of cheese in India is almost uniformly atrocious.

But I suppose that's more of a "cow" thing, than a "vegan/vegetarian" thing.

How did we get from vegetarianism to veganism?

It was me. Shame on me. I quoted someone talking about vegetarianism, and wrote veganism while talking about vegetarianism.
