In that case PoC should also have their differences and struggles acknowledged. They are significantly less likely to be employed, listened to, followed etc etc. Probably several other categories of people also should have their struggles acknowledged.
Or, you know, we could just assume that everyone on a show called Traitors knows they have to lie and be lied to. If they are not prepared for that, don't sign up. It's a bit like signing up to The Voice and complaining that you are a terrible singer, but you are a "good and decent person", and therefore deserve a pass.
As for this "centuries of women being lied to", watch Oz and US. Plenty of women lying and manipulating men wonderfully. British women seem not very good at it, but other nationalities are fabulous!
