AIBU to tell my mum to find her own racist knitting patterns

[gamerwidow]

I am currently embroiled in a disagreement with my Mum because she wants me to find her a knitting pattern for a golliwog.
I have tried unsuccessfully to explain that this not the innocent toy she thinks it is and have told her that I am staggered that she thinks it is anything but racist. She is only 70, she should know better.
She is now in a massive sulk.
Am I right or should i just have let her have her knitting pattern?

70 means she is the same age as that poor old dear Hilary Clinton, for context. David Bowie.
