I think the reality is, in Great Britain, and Europe, far too many animal rights advocates tend to have a disturbing attraction to fascist groups.
You, for example.
Hitler was a vegetarian, and promoted animal rights, and it still seems that traces of it are lingering in the atmosphere among Nationalist, and Nazi splinter groups. Morrissey endorsed Marie Le Pen of The National Front who spoke out in favor of animal welfare; which is no doubt the reason she secured Morrissey's endorsement This, along with the generic conservative distaste for immigrants, and other cultures.
Britain First also uses animal rights propaganda to attract fringe types without a political home, who treat it as a single voting issue. Morrissey the mark.
Morrissey sees meat eaters the way Hitler saw Jews. He's compared them to sub-humans, child molesters, the reason for war, and even supported the Animal Liberation Front's terrorism.
Hitler claimed that his disgust for the frailties of other humans was why he loved his dog more. A man who directed the murders of infants, and children had a soft spot for other living things. How sweet, and how...familiar.
