Liberal feminism is also called "mainstream feminism", "reformist feminism", "egalitarian feminism", or historically "bourgeois feminism", among other names. As one of the "Big Three" schools of feminist thought, liberal feminism is often contrasted with socialist/Marxist feminism and with radical feminism. Liberal feminism and mainstream feminism are very broad terms, frequently taken to encompass all feminism that isn't radical or revolutionary socialist/Marxist, and that instead pursues equality through political, legal and social reform within a liberal democratic framework; as such liberal feminists may subscribe to a range of different feminist beliefs and political ideologies within the democratic spectrum from the centre-left to the centre-right. The broader liberal feminist tradition includes numerous, newer and often diverging sub fields such as equality feminism, social feminism, equity feminism, and difference feminism, but liberal feminism also remains a tradition of its own; Nordic state feminism belongs to the liberal tradition.
