Feminism is generally defined as collectivist. “Reclaiming the F-Word“, to name just one recent publication on feminism, is quite clear that feminism is about collective action, collective gains, and a collective approach. If feminism is about collective action then those who focus on individuals rather than groups have a problem.
Conservatives and Liberals both tend to take an individualist approach. They start from a position of individual freedom and individual choice. With the exception of some strong socially Conservative ideas (which I don’t see as being representative of the current party), Tories tend to be pragmatic, without ideological or moral absolutes.
The problem with collectivism is that it assumes a simple, definable group identity. Collectivism quickly becomes essentialism, seeing members of the group as the same and willing into existence a definable feminine essence beyond biological characteristics. Firstly, belief in an absolute platonic form gives rise to reductionist issues hampered by the existence of individuals who do not fit into strict biological dichotomies. Secondly, women are half the population of the world: how can we be a group?
Starting from individualism doesn’t mean that collective action is impossible. It simply means that we work together, towards similar goals, in similar ways. It’s perfectly possible to believe in the primacy of the individual while still recognising the importance of the community.
