单选题肱骨干骨折常见的并发症

单选题It is true, as the movement critics assert, that the present women's liberation groups are almost entirely based among "middle class" women, that is, college and career women; and the issues of psychological and sexual exploitation and, to a lesser extent, exploitation through consumption, have been the most prominent ones. It is not surprising that the women's liberation movement should begin among bourgeois women, and should be dominated in the beginning by their consciousness and their particular concerns. Radical women are generally the post war middle class generation that grew up with the right to vote, the chance at higher education and training for supportive roles in the professions and business. Most of them are young and sophisticated enough to have not yet had children and do not have to marry to support themselves. In comparison with most women, they are capable of a certain amount of control over their lives. The higher development of bourgeois democratic society allows the women who benefit from education and relative equality to see the contradictions between its rhetoric (every child can become president) and their actual place in that society. The working class woman might believe that education could have made her financially independent but the educated career woman finds that money has not made her independent. In fact, because she has been allowed to progress halfway on the upward-mobility ladder she can see the rest of the distance that is denied her only because she is a woman. She can see the similarity between her oppression and that of other sections of the population. Thus, from their own experience, radical women in the movement are aware of more faults in the society than racism and imperialism. Because they have pushed the democratic myth to its limits, they know concretely how it limits them. At the same time that radical women were learning about American society they were also becoming aware of the male chauvinism in the movement. In fact, that is usually the cause of their first conscious 100 verbalization of the prejudice they feel; it is more disillusioning to know that the same contradiction exists between the movement's rhetoric of equality and its reality, for we expect more of our comrades. This realization of the deep-seated prejudice against themselves in the movement produces two common reactions among its women: 1) a preoccupation with this immediate barrier (and perhaps a resultant hopelessness), and 2) a tendency to retreat inward, to buy the fool's gold of creating a personally liberated life style. However, our concept of liberation represents a consciousness that conditions have forced on us while most of our sisters are chained by other conditions, biological and economic, that overwhelm their humanity and desires for self-fulfillment. Our background accounts for our ignorance about the stark oppression of women's daily lives.
