70% homo sapiens sapiens, 22% Variants, 8% assimilated aliens. General equality, with complete lack of any sorts of aristocracy (considered incompatible with american culture). Socially conservative, with conservatism seen as a guarantee of stability and enough births to replenish loses sustained during the wars.
While generally extremely liberal, American Empire does not extend Liberty to enemies of State. The collectivists - a common terms of all sort of 'statists', including fascism, communism, socialism or even social democrats - are persecuted relentlessly by security forces, and prone to 'disappearing'. Picturing political opponents as 'collectivists' isn't that rare, and was used especially often during the reigns of emperors who attempted to expand their power and play more direct role in politics.
Only religious organizations are allowed to lobby for any sort of non-radically liberal policies, with even Roman Catholic Church social teachings considered radically 'left' and sometimes shunned or distrusted even by its nominal members. The same situation is with worker's unions, that are allowed only if they are either religious or state-controlled, with no strikes allowed - in fact, they can be considered mostly a self-help organizations.
In terms of religion the state is heavily divided. It is also what makes the American Empire unique among its other Ancien Régime
peers is its general religious freedom that is considered a part of Liberty as a whole.
Ultimately, however, there are only certain religions that really fit in the American Empire's society. Circa 24% of population are adherents of Church of Unity from American Unity
, 17% are Roman Catholics, next 34% are two local churches - 19% are members of Church of Liberty while 15% are a part of Imperial High Church - with 7% Eastern Orthodox and 5% are baptists from churches not being a members of Church of Unity. Rest 13% are either non-denominational or indifferent.
