Naturally, there were many followers who took the opportunity to make their own digs at vegans in the thread, with Crafter Animations posting: "So many triggered vegans lol." And Twitter user Darxion added: "Absolute ripper of a response. I'm a member of this PETA too then!"

Veganism is a growing trend worldwide and is especially common in the UK, with the BBC reporting the number of vegans had jumped from 150,000 in 2006 to 542,000 in 2016.
The spike has been helped by the popular "Veganuary" campaign, which encourages people who aren't vegans full-time to give up animal products during January.
Around 78,000 people took part in Veganuary in the UK last month.
