Morrissey has always linked his depression to seeing footage of animals slaughtered & admits vegetarianism/veganism can be hard.
I became vegetarian first when I was very young when I caught sight of a programme on the television showing slaughter and I’d never seen it before, the abattoir, the slaughterhouse. I was frozen for five years. I couldn’t believe that in our society such places exist. Even now I can’t believe such places exist. It baffles me, I can’t understand it. Nobody’s that hungry that you need to take a life of something that also wants to live. It’s a gradual thing. Everybody begins as vegetarian because to dive straight forward into being a complete purist is very hard for most people. Financially you can’t do it and also you have to find food, but once you do it it’s so much better. [Takes off Stella McCartney shoe] There’s no animals involved in this shoe but from a distance you’d think it was an animal shoe. It’s not made of leather, it’s plastic. Would I really lie about this? Is this the place to lie about shoes? (Morrissey, Larry King Now, 19 August 2015)
Despite that, he’s always been attacked for it.
30 March 1985: Following the Morrissey interview (Trial By Jury) featured in the Melody Maker on 16 March, there was a strong reaction against the singer in the letters column. “Will MM give us a break from Mr Righteous God Almighty Morrissey?”… “Morrissey you ain’t seen anything if the Lunatic Animal Libbers kill any of my kids”… “MM could solve most of Morrissey’s problems by arranging a confrontation with a full-grown lion, a Bengal tiger, an alligator, or some other carnivores to see if his platitudes can influence their diet!” (Johnny Rogan, the Smiths, Omnibus Press, 1994)
And the press even managed to use it in their quest to brand him a gay predator/racist.
The holier-than-thou aspect of Morrissey’s public profile has naturally tempted journalists to try and bring him down… Some have unsuccessfully tried to brand him a racist… The other line has been to probe for a story on the man’s sexuality, taking their cue from the camp artwork on Smiths record sleeves… (Stuart Bailie, Record Mirror, 14 February 1987)
With his last album called Years of Refusal, Morrissey is nothing if not defiant, and I suspect that his unattractive response to being challenged over race in the past is to grow ever-more certain of his own righteousness and then court fresh controversy in order to confirm to himself that he is being persecuted. What the world thinks – and the feelings of others – are nothing compared to the importance of being Morrissey.

His outsiderdom is a function of his misanthropy. And his vegetarianism is the expedient by which he justifies that misanthropy. (Peter Paphides, the Guardian, 10 March 2012)
British rocker Morrissey forced Madison Square Garden to ban meat and fish when he gave a concert there last year. “There is no difference between eating animals and pedophilia,” he’s said, and once actually likened the use of animals for food to the Holocaust. His self-righteousness inflames Yvette d’Entremont, an LA-based analytical chemist who debunks many nutritional myths — especially those which claim just about every food to be dangerous… (Steve Cuzzo, New York Post, 18 May 2016)
Yet even that song’s (brilliant) sad-bastard rallying cry—“I am human and I need to be loved / just like everybody else does”—sounds like an understatement in comparison to “Meat Is Murder”’s sanctimonious refrain: “It’s death for no reason / and death for no reason is murder.” (Erik Adams, AV Club, 28 January 2015)
While it’s one thing for an artist to insist on vegetarian catering for themselves, it does seem rather extreme to demand that those working at and attending the show must also adhere to their food preferences... But it’s Morrissey and it seems that promoters are prepared to put up with such food fascism.

…they assume you’ve adopted the moral high ground by refusing to eat a dead animal. And they’re right. But you only take the stand on behalf of the butchered animal, you don’t make money from your point of view. You become the voice of the animal… who kicked and struggled to hang on to life, but who was chopped up because some fat oaf in Woking fancied some commercial-break nibbles (Morrissey, Tremr, 5 June 2018)
