Sadly, oppression exists across all of society - with many sectors experiencing unfair treatment, including the LGBTQ community.
According to TV journalist and author Jane Velez-Mitchell: "The LGBT community knows what it’s like to be voiceless and to be treated as 'less than'.
"No group of sentient beings is more exploited and neglected than the billions of cows, pigs, lambs, chickens and turkeys trapped in factory farms."
Here are some LGBTQ celebrities that rep the vegan status.
1. Simon Amstell
English comedian and TV presenter Simon Amstell - who made headlines when he released his vegan mockumentary, Carnage: Swallowing the Past, this year - is openly gay and a teetotal vegan.
The 37-year-old stand-up comedian believes in the power of compassion, saying: "If you don't feel empathy for the cow or the pig who is having its throat cut or being shot in the head, then I just don't know.
"I think that a lot of the world's problems could be resolved through empathy, through letting go of the idea that you are the most important person in the world. Which is a very difficult thing to do because we definitely think we are.
"The answer is, most definitely, compassion."
A vegetarian for years and vegan since 2014, Sia Furler has expressed her sexual fluidity in the past.
