We'll see if any of the lib media organs reproach De Niro for his infantile, vulgar behavior.
What are the chances?
Probably zero.
Of course, if it had been a conservative celebrity at some public function saying that about Obama, all the lib rags and outlets would be in an uproar condemning the speaker and urging immediate exectution on the guillotine. I'll bet many of the people in the audience standing and cheering Travis Bickle's remarks work for the Slimes or other lib media organs.
