As discussions about racial injustices continue to swirl in the sports world, tennis superstar Serena Williams chimed in with a Facebook post Tuesday.

Following the lethal shootings of Philando Castile, Terence Crutcher and Keith Lamont Scott by police officers in Falcon Heights, Minnesota; Tulsa, Oklahoma; and Charlotte, North Carolina, Williams said she will continue to speak out about social inequality:

This is not the first time Williams has used her platform to try to combat inequality.

In a first-person piece for Wired in November, Williams encouraged people to remain invested in vanquishing hate.

"So to those of you involved in equality movements like Black Lives Matter, I say this: Keep it up. Don't let those trolls stop you," she wrote. "We've been through so much for so many centuries, and we shall overcome this too (see 'Get Up, Stand Up')."

Williams' comments came a day after the Cleveland Cavaliers' LeBron James discussed how police shootings have affected the way he thinks about his son, who is in sixth grade, driving on his own in a few years.

"You tell your kids, 'If you just listen to the police that they will be respectful and things will work itself out,'" he said, per the New York Daily News' Ebenezer Samuel. "And you see the videos that continue to come out. ... It's a scary-ass situation, that if my son calls me and says he's pulled over, that I'm not that confident that things are gonna go well and my son is gonna return home."
