The cold hard fact of the matter is that people are different.
In terms of insurance, we are sepperated by much more than gender. Seperated by age, gender, previous history. Be that health, driving convictions or even genetics. Even if we smoke or are obeese. Insruance works by fitting people into catergories. You take on 100 people 10% will be high risk the other less and that is how it works and there is always enough money in the pot to cover expeneses.
Its madness to say I should pay the same as a 45 year old man who has never had a claim just as its silly to suggest that I should pay the same as a 26 year old boy racer. Just because we are the same age and we can no longer discriminate on gender.
The whole process of insurance is about discrimination. Even if it is positive discrimination. It is baised on calculated risk. Which does involve many areas such as gender and age and social status even. If there is no discrimation in insurance I can only see that those whodont need to will be paying more and no one will be paying less
