So Danny boy is suing over an article http://mirror.washingtoncitypaper.com/articles/40063/the-cranky-redskins-fans-guide-to-dan-snyder.html
He didn't like people saying things he didn't approve: http://mirror.washingtoncitypaper.com/blogs/citydesk/2011/02/02/snyder-sues.html
So he objects to the squigly lines drawing devil horns and a goatee on his image because they're anti-Semetic. Dan Snyder, you see, is very sensitive towards depictions that may be racist and culturally insensitive nature.
