Erika "Jayne" Girardi clapped back hard against a social media hater who insinuated she's not fully supporting Black Lives Matter because of her son's profession.
Tommy Zizzo, the son of "The Real Housewives of Beverly Hills" star, is a police officer.
On Tuesday, Erika joined the Instagram "Black Out," in which users shared blank black screens, a show of support for Black Lives Matter and peaceful protesting.
One particular user commented, "Your son is an officer!"
Erika shot back, "My son was brought up NOT to be racist. His job is to protect and serve ALL not just people that have his skin color."
In a parting shot, she added, "F–k you and stay off my page."
Many of Erika's 2 million followers applauded her fiery response.
"People need to understand that being against police brutality doesn't mean you are against police," one person said.
Another added, "Man I thought I loved you before but hell yes."
After she shared more messages from people supporting her clap back on her Instagram Story, the reality TV star added that her initial critic had now "blocked" her on Instagram.
Erika typically shies away from sharing images of her son on social media, but she posted a picture of him in uniform on May 5.
"People say we look alike," she wrote. "No, you can't comment."
She later told Andy Cohen that she posted the image to show her pride.
"I put him on Instagram and he's my best-performing post," she said. "He didn't choose this life, I chose this life, and you try to protect them. I don't care if he is an adult and he carries a gun and a badge. At the end of the day, he's still my boy, but I posted it and I'm glad I did. He is a very fine young man and I'm so proud."
