Given that most vegans are morally opposed to any kind of animal suffering, I would think running an abattoir would be anathema to them and the best reasonable course would be to shut down the abattoir in an orderly fashion. If one is appointed as the manager, it sends a certain message to the workers that they might not like.
They can be opposed to animal suffering, and therefore interested in animal welfare from birth through to slaughter - they can accept the realities of the food industry, and the freedom of people to eat meat without giving up the principles that guide their own choices.
This appointment sends a message to farmers and the public in general that meat farming and production is to be discouraged; the new shadow minister has claimed that meat farming is a waste of resources (not always the case, not all land on which you can farm animals is suitable for arable).
No, this appointment sends a message to farmers and the public that they have a shadow minister that is interested in animal welfare and doesn't just see the financial bottom line. Meat farming is more resource intensive than other crops, and although not all grazing land is suitable for agriculture much of it is.
If that is the message that Corbyn wants to send, it is fine by me, even though I don't agree with it and I certainly wouldn't claim that this makes Kerry McCarthy unsuitable for her job.
But then, if you've decided what their message is before they've had the opportunity to tell you for themselves, then your judgment of her suitability for the job is just you being judgmental, not a reasoned response to the situation.
