That Vegan Teacher

Kadie Karen Diekmeyer (born September 24, 1964), popularly known as That Vegan Teacher, is a Canadian animal rights activist, internet personality and former educator, mainly known for promoting veganism.

Before she started her online career, Diekmeyer was a nurse and later an ESL teacher but eventually left the latter job at the start of the COVID-19 pandemic.

Diekmeyer is known for her TikTok and YouTube accounts that promote veganism.

Diekmeyer's content has been controversial, prompting accusations of racism and homophobia.

Diekmeyer was born on September 24, 1964, in Montreal, and is of German and Swiss descent.

Diekmeyer worked as a registered nurse at the Lakeshore General Hospital for 25 years, and attended Concordia University to become an ESL teacher in French Canadian schools for nine years.

She worked both jobs before dropping her nursing career to work full time in the school system and eventually leaving her job at the start of the COVID-19 pandemic.

In 1995 Diekmeyer composed the nationalistic English-French folk song "Imaginez un Pays/Imagine a Country" and performed at the Unity Rally at the Place du Canada.

She spoke of her anxiety before her public performance, which she had never done before, and got help from her friends and relatives to write the French lyrics.

Cheryl Cornacchia of the Montreal Gazette called her "one of the dozens of do-it-yourself artists making a place for themselves in Montreal".

As of 1999, Diekmeyer had written 47 songs, mainly about life and women's empowerment.

Diekmeyer is known for her TikTok and YouTube career of promoting veganism.

Her open letter, "Dog persuaded them to give up meat", censuring cruelty to animals, was published in the Montreal Gazette in 2004.

She has three children with her first husband.

She remarried on December 4, 2021, following a courtship of nine and a half years.

She has also voiced negative views on circumcision, calling it child abuse.

In April 2023, she moved to Italy.

A vegan since June 27, 2016, she condemns what she considers to be vegaphobia.

She went viral on TikTok for a song called, "Eating Animals is Wrong, McDonald's", in July 2020.

Some of Diekmeyer's content has been characterized as racist and homophobic, including the repurposing of the slogan of "I can't breathe" for a song expressing opposition to animal agriculture, as well as arguing that coming out as LGBT is a selfish act as opposed to doing so as vegan.

Diekmeyer has also drawn criticism for comparing the animal agriculture industry to the Holocaust.

In September 2020, she was criticized for saying she would no longer sign her organ donor card, "not [wanting] to donate [her] organs to meat eaters after [she] dies".

In March 2021, she made a YouTube video, titled "Are You Racist?", in which she spelled out the word "nigger" in an acrostic poem and encouraged people to "ban cruelty instead of words."

Another controversy arose in result of Diekmeyer's comment on a 2021 TikTok video by gaming YouTuber TommyInnit, where he talked about his YouTube Play Button.

Using TikTok's stitch function, she responded, "Tommy! The nice vegan girls don't want to see your buttons, but if you want them to play with your buttons, you're going to have to show them your fruits and your vegetables," while taking out a cucumber, pear, and apple.

This sexual joke enraged people online, owing to TommyInnit's age, then 16.

Diekmeyer defended herself, claiming she "had no idea who he was," and that [at his age], he was considered a "college-age student" in Canada.

Later that year, she was IP banned from TikTok after being mass-reported for breaching community guidelines, though the exact cause was unknown.

Diekmeyer posted a video on her YouTube page, promising to not give up on her platform.

She has made more TikTok accounts but ended up with most of them being banned.

Diekmeyer is bisexual.

She speaks English and French.
