Even if we refuse to believe that social-hygienic teaching will protect many young men from sexual diseases, there is the woman's need of information to be considered. As said before, women more than men suffer the consequences of venereal infections. Therefore, every young woman who considers marriage should know the possibility of danger to herself and her children, and be able to decide accordingly. Of course, even with much knowledge she may marry the wrong man, for correct diagnosis of social disease is not always easy; but if her confidence is betrayed and she becomes infected, she ought to know the importance of immediate and radical medical treatment. Let me illustrate these statements that women should know the danger of venereal disease. One of my college friends neglected an important legal case to travel seven hundred miles in order to tell face to face another college friend that she was about to marry a dangerous man. Being utterly ignorant of the existence of sexual diseases, the girl and her mother characterized my friend's statement by a short and ugly word, and ordered him to leave their home instantly. The marriage occurred and some months later the young woman went to her grave, a victim of gonorrheal salpingitis and peritonitis. Another case which illustrates the danger of a woman's ignorance: One of my students of many years ago married a minister who infected her with syphilis and kept her from medical attention until the disease was in a highly developed stage, and even then conspired with an inefficient doctor to keep her ignorant of the nature of the disease. [Sidenote: The right to knowledge.] These are not extreme cases, for any physician with large experience knows that such things are common. Medical literature is full of such painful recitals of venereal tragedies. It is not desirable that all young women should know the details of such tragedies, but they should know that dangers exist. Parents and educators will not have done their duty until they cooperate to give all young women the protective knowledge they have a right to demand.[4] [Sidenote: Best people must lead.] There is another way of looking at the possible effect of the social side of sex-hygienic instruction. It is sure to make a decided impression upon many young people of the type that we regard as the best in every way. These will be the leaders of the future and they in turn will help improve conditions. Perhaps it may all work out as the drug problem is being solved. Widespread social and hygienic information regarding the harmful effect of alcohol, cocaine, opium, and other drugs has first of all impressed leading citizens; and these are beginning to control by laws those who cannot be reached directly by education. In some such ways those who are impressed by formal sex-education may lend a hand in influencing many who could not be touched directly by hygienic education. [Sidenote: Legislation needed.]
