A doctor in CA advertises that he performs vasectomies, a very safe and common elective procedure. Say several healthy, single, childless, young men (<30) go to see the doctor asking for a vasectomy procedure. Say the doctor refuses to perform a vasectomy on all of these men. The doctor says his reason for denial, in each and every case, is that they are " too young." The doctor says he is afraid that the young men might change their minds about fathering thier own children and regret the procedure later in life. Would this be a case of class discrimination? The class being young childless men.
