The Friday Night Lights director posted a meme about Jenner's Arthur Ashe Courage Award win shortly after the reality TV star picked up the accolade in Los Angeles.

The instagram post featured side-by-side photos of Jenner and an Army veteran and double amputee, who appeared in Berg's film Battleship along with the caption: "One man traded 2 legs for the freedom of the other to trade 2 balls for 2 boobs. Guess which man made the cover of Vanity Fair, was praised for his courage by President Obama and is to be honored with the Arthur Ashe Courage Award by ESPN?"

Berg added, "Yup", suggesting he agreed with the original writer's sentiments.

On Thursday (16Jul15), the moviemaker returned to social media to clarify his intentions behind posting the meme, writing, "I have the utmost respect for Caitlyn Jenner and I am a strong supporter of equality and the rights of trans people everywhere.

"I also believe that we don't give enough attention to our courageous returning war veterans, many of whom have sacrificed their bodies and mental health for our country and our principals - principals that include the freedom to live the life you want to live without persecution or abuse."
