Riley's overwriting of Jeremy's anti-apartheid banner with her disingenous slogan is symbolic of the eclipse of other forms of racial prejudice by those who have pushed the hysterical antisemitism accusations against Labour with monomaniacal fury.
Something similar happened when Ian Austin and John Woodcock, in the name of anti-racism, urged voting for the party of Windrush. To bring things full circle both are friends of a state running an Apartheid like regime in occupied Palestinian land.
