Jon Holmes had a somewhat heated debate with a National Union of Students (NUS) Scotland member over "cultural appropriation" of Halloween costumes.
The debate erupted after a parenting activist, Sachi Feris, wrote that dressing kids up as the Disney character Moana would be "cultural appropriation".
In the same blog post, she explained her fears of promoting white privilege through letting her daughter dress up as Elsa from Frozen.
The post sparked global debate, and to discuss the topic, Shuwanna Aaron from NUS Scotland came onto talkRADIO to speak with our host.
She said: "The issue at hand is that it's incredibly offensive to wear someone's culture or part of their identity as a costume.
"Inherently a costume is something abnormal, something that is comical to wear.
"If what you're wearing is a part of someone's identity, you shouldn't wear it.
"Halloween's a time for fun, but not when it's mimicking a side of someone's attention, in a place where it could be uncomfortable."
Aaron called it "incredibly damaging", and Jon challenged her to explain that to a seven-year-old who wanted to wear a Moana costume.
