Ideological discrimination may be on the grounds of political, religious or other ideology, and may include unequal voting rights or the banning of political parties and religious sects. Discriminatory actions may be taken when a particular political party comes to power and wishes to consolidate its position, by denying political power to its opponents and at the same time rewarding its own members and supporters. Discrimination reinforces existing social prejudices, inequalities and injustice, and may lead to violence or even war.
