According to author Mark Hertsgaard , " Piggies " " kept the Beatles ' countercultural flame alive " , as the song was embraced as an anti-authoritarian anthem by the counterculture , following a year of protests and civil unrest in many Western countries . Among many such events in the United States , police officers clashed violently with anti-Vietnam War demonstrators at the Democratic National Convention in Chicago in August 1968 . David A. Noebel , an American arch-conservative , paired the song with " Back in the U.S.S.R. " when he accused the Beatles of being pro-Communist and leading a move towards revolutionary socialism with the White Album . Along with McCartney 's " Rocky Raccoon " , however , " Piggies " was also criticised by the radical New Left as an example of the Beatles resorting to whimsical parody instead of directly addressing contemporary issues
