This topic has been confusing me quite a bit, on a lot of RP literature (manipulated man, misandry bubble) etc they claim that women in the UK are worse than women in the US. I've heard it thrown around quite but no one has really given me the specifics as to why.

Initially I believed that it was just from an american standpoint that British women are worse due to the negative effect being american can have on your SMV with British women compared to the positive effect american nationality can have with your interactions with Russian women. But I've heard this trope being used outside of the realm of SMV (the manipulated man) so I would like an explanation as to why British women are worse than other western countries?
