A mother of three who was racially abused by another supermarket shopper while shopping with her 12-year old dauther, fears little has been learned from the Christchurch mosque terrorist attacks, says Stuff. A spokeswoman for New World defended staff’s handling of the incident, saying the customer was understood to have a mental condition. But Melanie Sharma-Barrow, who endured multiple slurs directed at her and her child, said mental illness and racism were not synonymous and it was too often used as an excuse.
