In July 2015 Berg posted an image of Caitlyn Jenner and double amputee Colonel Gregory D. Gadson on instagram with the words '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'.  He was criticised for attacking Caitlyn Jenner, but claimed he was trying to draw attention to the plight of US veterans.
