According to Charlotte Bunch, a lesbian is a person who rejects the male sexual and political domination. Lesbianism threatens male supremacy at its core. A lesbian is a woman who connects herself and supports other women in a political, emotional, physical and economic way.
A lesbian commits herself completely to other women to escape the oppression of a male/female relationship. Bunch believes that women who do not commit herself to other women, including sexual love, accept their status as a second class citizen. Women are to not have any heterosexual contacts with men. By being a lesbian it allows women to escape person oppression and submission. Because men depend on females for support, by taking it away it will force the oppression to break down, shattering their destructive privilege over others. In other words it is the key to the liberation of women, because being a lesbian mean “ending identification with, allegiance to, dependence on, and support of heterosexuality.” (86)

This is what Bunch says lesbianism is. Do you find her definition convincing? Her essay is from several decades ago. Do you think the definition of lesbian has changed over time? How?
Lesbianism, according to Bunch, is no longer a personal or sexual category but now a political category. Is this ideal? Does heterosexuality or male homosexuality have (or should have) a particular political identification attached to it?
Are these sexuality differences arbitrary, or do they govern an individual’s consciousness in a regulated, recognizable, and conforming manner?
“women who do not commit herself to other women, including sexual love, accept their status as a second class citizen” I am not a second class citizen.Buff!
