Yes, the PM is a woman, Ireland has a gay (I think ethnic minority) Taoiseach, and those are great things on a representational basis. The US had a black president. Then they elected a misogynistic racist to follow him. In France the Nazi candidate got 25% of the presidential vote. In Austria it was 45%. On a daily basis, May and Obama have to put up with vitriol that no white male politician experiences. Obama had to go through ten years of people refusing to believe that he was actually eligible to be president, of people claiming he was Muslim, of repeated racist attacks. May, Thatcher, Hillary Clinton, have to put up with interminable articles about how they dress, whether they smile enough, whether they are too feminine or not feminine enough. They get questions of who looks after the children, which would never be asked of a male politician.
Women make up around 52% of the population but, as of 2010, only 22% of MPs were women. 13% of people living in the UK are of ethnic minorities, but in 2010 only 4% of MPs were. The numbers are similar for directors of FTSE companies. Women, accounting for age, profession and experience, earn roughly 15% less than men, across the board. People of colour also generally earn less than white people.
