Vegan 'celebrity' Durian Rider's abhorrent views are just the tip of the iceberg. Credit:YouTube/Durian Rider Veganism is growing. That is a good thing. What isn't so good is that as the community grows, so too does its disregard for anyone who isn't an able-bodied, middle-class, white person. Rider and his partner Leanne Ratcliffe (better known as Freelee the Banana Girl), champion the "Raw till Four" diet, basing much of their advocacy on fat-shaming, with Freelee frequently claiming she just "has to speak up" when she sees people "abusing themselves via the fork". In this myopic interpretation of veganism, there is no valid option to being to hot and skinny. Obesity – along with cancer and even mental illness – are callously blamed on the failure to "carb the f--k up" on a vegan diet and little sympathy is granted to anyone who doesn't heed their message.

But Ratcliffe and Rider have nothing on Gary Yourofsky, an American whose modestly titled lecture, The Greatest Speech You Will Ever See, made such an impact in Israel, it is credited with sparking off a vegan revolution in that country. Consequently, Yourofsky spends much time in Israel, where he has developed outlandishly racist views on Palestinians, calling them the most "psychotic group on the planet". A self-described misanthrope, Yourofsky exhorts his followers to focus only on the plight of animals and "forget about those Palestinian maniacs". This is the core of what is wrong with the mainstream vegan community today. So many of its adherents refuse to make the connection between human oppression and the exploitation of animals. When people first become vegan, they tend to seek out the company of other vegans. It's a vital support network for what can be a very isolating experience. Once you have opened your eyes to the extent of the suffering we inflict on animals, your world is never quite the same. The grief is real and it is intense. Unfortunately, mainstream veganism is not always a safe space for people of colour, feminist women, the disabled, and those who don't fit the conventional model of attractiveness.

I've had to leave pretty much every online vegan group I was involved with because I couldn't handle another discussion about how fat vegans make other vegans "look bad", or about how vegan food is so cheap that all poor people, even those living in areas like the infamous food deserts in the US, had "no excuse". Speaking of excuses, I got tired of those made for groups like PeTA, which despite its vital and tireless work advocating for animals in slaughterhouses and laboratories, still insists on exploiting and objectifying women. I found myself endlessly frustrated with a movement that readily appropriates the struggles of other groups by comparing factory farms to slavery, but ignores the voices of people of colour when they object to white vegans – such as celebrity vegan chefs Thug Kitchen – profiting from racist stereotyping of black people. I am disenchanted that a movement that is comprised mostly of women nonetheless elevates white men to most leadership positions. Men such as Professor Gary Francione who thinks it is his place to lecture women on whether or not they can call themselves feminists. And I'm dismayed that critiques of prominent vegans are routinely shut down because these men are "doing so much for the animals". All of which leaves me asking how a movement that emerged as a direct challenge to the ideals and excesses of western capitalism could do such a thorough job of emulating it.

Of course, in this veganism is not alone. The white capitalist system is remarkably adept at not only neutralising challenges to its existence but at absorbing them to make itself stronger. It is ironic, for instance, how the push for marriage equality brought that dying institution back from the brink to the thriving mega business it is today. Same-sex couples still can't get married in Australia, but everyone else is. There's also the way radical feminist critiques of female objectification have been shouted down by shallow declarations of female empowerment. But when riot grrl gave way to girl power, you know it was because someone was making a lot of money. But what sets veganism apart from other movements is that it is the only one that advocates on behalf of a group that cannot speak for itself. And that makes it even easier for wider society to ignore. The acceptance of veganism into the broader social justice movement hinges on bridging this gap. And no one is better placed to do so than those vegans who are most marginalised in society – people of colour, women, LGBTI, fat people, disabled people. Indeed many, such as Sistah Vegan creator A. Breeze Harper, disability advocate and artist Saunara Taylor, and ecofeminist pioneer Carol Adams, already are. That their voices are drowned out is a tragedy not only for these tireless activists but for the animals that all vegans wish to save.
