In her post, Kim stated that she had previously felt uncomfortable speaking out against police violence against black Americans because of her privilege as a non-black celebrity. However, George Floyd's death caused her to put those reservations aside, she wrote.
"Like so many of you, I am angry. I am more than angry. I am infuriated and I am disgusted," she added.
She later expressed empathy for the families who have had to live with the emotional trauma of losing a loved one at the hands of the police.
"Even though I will never know the pain and suffering they have endured, or what it feels like to try to survive in a world plagued by systemic racism, I know I can use my own voice to help amplify those voices that have been muffled for too long," she wrote.
In her caption, she encouraged her followers to text "Floyd" to a number that directs them to a petition demanding justice for the deceased 46-year-old Minnesota man.

"Thank you for speaking up Kim! we need you at this time," a supporter added.
"Your voice matters more than you'll ever know," a third commented.
Kim also received support from a fellow celebrity, actress/media personality La La Anthony.

This is hardly the first time that Kim Kardashian has expressed concern about social justice issues. She famously championed the case of Alice Marie Johnson, a woman who had been serving a life sentence in prison for a minor drug charge. Kim's involvement which included a meeting with President Donald Trump helped secure Johnson's release in 2018.
In a recent documentary called Kim Kardashian West: The Justice Project, the reality TV superstar also opened up about her continued advocacy for men and women who have been unjustly incarcerated.
