[9][10][11] On April 28, 2021, Dave Leduc criticized Muay Thai fighter Buakaw Banchamek and historical figure Nai Khanom Tom in a social media post.

Leduc questioned the veracity and claimed that the Nai Khanom Tom folklore story is exaggerated and that he was simply a prisoner in ancient Burma, referring to Siamese prisoners captured by Burmese troops during the Burmese–Siamese War.
