Serena refuses to stay silent on police brutality

Serena Williams took to Facebook to pen her thoughts on police brutality and why it's so important to speak up, ending her powerful note with "I Won't Be Silent." She was being driven by her 18-year-old nephew when she thought back to the July 6 fatal shooting of a black man during a routine traffic stop in Minnesota.

"I would never forgive myself if something happened to my nephew. He's so innocent. So were all "the others," Williams writes.

The 35-year-old is far from the only one sensing the rising tension between authorities and minorities, but her platform is greater than most.

"Why did I have to think about this in 2016? Have we not gone through enough, opened so many doors, impacted billions of lives?" Williams asks. "But I realized we must stride on- for it's not how far we have come but how much further still we have to go."

Using her astounding fame and following (case in point, nearly 5 million Facebook likes), Williams has successfully related to all aunts, uncles, mothers, fathers and siblings with inspiration from the one and only Martin Luther King, all in one simple social media post.

This isn't the first time Williams has spoken up. She voiced concerns over her nephews' safety at Wimbledon after shootings in Dallas.

“I feel anyone in my color in particular is of concern," she said. "I do have nephews that I’m thinking, ‘Do I have to call them and tell them, don’t go outside. If you get in your car, it might be the last time I see you?’”

No matter how many Grand Slams you've won, you're not immune from feeling fear in what should be a very normal daily situation. No matter how much money you're worth, you can refuse to be silent.
