First, as pacifist I don’t tolerate violence.

In addition, that already means that the group has nothing related to veganism, which is an ethical principle based on the respect inalienable interests of individuals which, even with a focus on non-humans species, also would cover that.

Second, there is no such thing as personal choice when what you do affect other individuals rights, including non-humans with consciousness.

The first part and this already set that veganism is not a “food choice”, with a main reason explained in the paragraphs before and other because it drives the individual moral under it.

Based on that, what this people try to do there, opposing to that, and what the reactionists do, has no sense.
