Explanation:
Chelsey Handler hosted a TV Show called Chelsea Lately (broadcasted from 2007 to 2014).
On June 20, 2011, she talked in that program about a singer called Amy Winehouse's concert performed in Belgrade, Serbia. That concert was criticized by Serbian Defense Minister "calling Winehouse's performance a 'shame and a disappointment'. Handler then stated, 'Well, so is your country'" Chelsea Lately (2020), in Wikipedia.
After that, there were two petitions on the internet, made by Serbians, called for a boycott of Chelsey Handler and the TV channel E! until she and the channel publicly apologize for that (Chelsea Lately (2020), in Wikipedia).
