A teacher in the US has gone viral for his response to a student's question about JK Rowling’s supposed transphobia.

Warren Smith was asked if he still liked the author’s work despite her “bigoted opinions”, and the video of his reply was shared by Elon Musk on X.

Mr Smith joined Sky News Australia host Piers Morgan to discuss the clip.

“This came out accidentally, we have interactions like this on a daily basis – this one just happened to be captured on camera," Mr Smith told Sky News Australia host Piers Morgan.

"This is about more than JK Rowling, it's the realisation that his prior assumptions, he was going off of 'well I've heard that this is true, so many people have told me that this is true'.

"And when you experience that for yourself and it crumbles, then you have to question, logically what else am I assuming to be true that perhaps might not be, and that changes the way you view the world."
