For the same reason I'm opposed to sex-ed class in schools, I'm opposed to clubs like this. A parent sends his students to a public school to receive a rigorous education in the core curriculum. Parents should not be forced to send their children to public schools that allow controversial subjects--unrelated to science, math, geography, etc.--to be a part of the school environment. Such subjects distract from what needs to be occurring in classrooms and often isn't: learning.
Will Okun, who teaches school in Chicago, blogs at the New York Times:
I do not understand why society and parents rely on our much criticized, overcrowded and under-funded schools to teach children about such important issues as abstinence and safe sex?
