The term you are looking for is protected class. When gender based discrimination is outlawed men are included as well. That being said Montana outlaws gender based discrimination in auto insurance as does the EU. Where its allowed it is allowed because nobody got around to outlawing it. That can change. Until Obamacare many US states allowed health insurance companies to charge women higher premiums because women go to the doctor more. Obamacare outlawed that. I think gender discrimination is auto insurance will end eventually.
