Following an Instagram argument with "fit mom" Maria Kang over body-positivity, plus-size model Tess Holliday took to her Twitter account late Thursday to criticize people for using her name to sell "weight loss scam."

"Tired of these ppl using my name to sell their weight loss scams. Sis, losing weight ain't gonna fix the hate in your heart," she wrote along with a GIF.

Holliday went on the Twitter tirade allegedly attacking Kang for not understanding feminism and also those who were confident about their size.

The argument ion Instagram started Monday after Kang, who is a fitness blogger, responded to Holliday's comment on Robbie Tripp’s viral post about his curvy wife.

Holliday slammed Tripp after he shared a photo of him and his wife, Sarah, embracing each other on the beach, writing that he loves her despite her size. As thousands of Instagram users praised the “Create Rebellion” author, the 32-year-old model said that people should stop praising men for doing the bare minimum.

Responding to this, Kang criticized Holliday for her body size, and also for not promoting positivity.

“Did anyone read this story about a husband loving his wife regardless of size? I thought it was a sweet tribute of someone loving their spouse despite any standard. When I see someone like Tess Holliday criticize this, it's disheartening. Tess is an obese model (not thick, plus size or curvy) who has popularized the term #effyourbeautystandards and should promote positivity in all forms,” Kang wrote.

Some users sided with Holliday while others supported Kang.

“He should not be praised for loving his wife 'even though' she's not thin. That should be given. He doesn't deserve an award for being so accepting … she is gorgeous and he's lucky to have her,” one Facebook user commented, while another wrote: “Props to this man for supporting and loving his wife regardless of her size, but I sincerely hope that if his ‘curvy’ wife gets to the point where she's becoming unhealthy and/or obese, that he would encourage her to eat healthier and get moving, not because of the way she looks, but because of the dangers of being grossly overweight.”

While talking to Yahoo Beauty, Kang said about the heated social media argument: "Tripp’s post was a sweet tribute to his wife, but we live in a highly sensitive culture where people want to be applauded for self-acceptance rather than accept it from someone else,” she added: “It seems like Tess believes it’s anti-feminist for a woman to want approval from any man. She has a hard, militant stance regarding outside validation, as symbolized in her #effyourbeautystandards campaign.”
