Meyers Leonard of the Miami Heat was caught red-handed saying a vile anti-Semitic racial slur on a video game stream he helped organize on Tuesday, causing a furor in the NBA world.

With the NBA focusing much of its efforts on fighting for social justice and bringing attention to the issues facing minorities on a daily basis, Leonard’s remarks were unforgivable to some.

After Leonard issued an apology, which came a few hours after he made the terrible remark, the sister of Oklahoma City Thunder veteran Al Horford, Anna Horford, chimed in with a NSFW response.

As you can see, Horford didn’t care much for Leonard’s apology, and when she was pressed by a Twitter commenter, she provided more context on why she felt that the Heat center’s contrite response was less than adequate.

“He made an excuse when he said he ‘didn’t know what it meant’ and he’s apologizing because he got caught. If he truly wants to change as a human being, we’ll see it in his future actions. Until then, we have alright to be skeptical. When people show you who they are, believe them.”

Listening to the audio of Leonard’s slur, he paused beforehand as if he was aiming for a dramatic effect. Whether or not this was the case, it certainly didn’t help his cause.

Also going against Meyers Leonard is the fact that he infamously refused to kneel during the national anthem in the NBA Bubble, saying while he supports the Black Lives Matter movement, he also supports the military and the people who have fought to defend everyone’s rights in the US.
