 In 2005 , the <unk> Center for Arab Rights in Israel paid for ads on television and radio stations in Israel . In the television ads , the Arabic phrase for " have a nice day " would flash onto the screen in black letters and on a red background . Immediately following the Arabic phrase would be a Hebrew phrase that said , " Are you already against it without even knowing what it says ? All we wanted to say is have a nice day . " Spokeswoman Abir Kopty stated that " [ t ] he purpose of this campaign was mainly to cause the Israeli public sitting at home , or walking down the street , to ask itself why it had a negative reaction to everything Arab , even if it is the simplest phrase . " Kopty further said that the <unk> Center wanted to encourage Arabs to be more active and more visible in the community .
