NBA superstar LeBron James suggested Friday that Boston Celtics center Enes Kanter is not a man because Kanter has not directly confronted him over criticisms involving Nike and China.

During a game between the Los Angeles Laters and Celtics on Friday — in which the Celtics beat the Lakers 130-108 — Kanter wore shows that depicted James bowing to Chinese President Xi Jinping, who places a crown on James’ head.

Kanter, in addition to being a highly successful basketball player, has made a name for himself by publicly criticizing brutal regimes, like Turkey, the country of origin for his family.

In recent months, however, Kanter has stepped up his criticism to include China. Kanter has called Jinping a “brutal dictator,” and he has declared support the “Free Tibet” movement. Kanter’s criticism of China has included taking aim at James, who plays for the Los Angeles Lakers and has a highly lucrative endorsement deal with Nike.
