For over thirty years, Learning as the Constant and Time as the Variable has been a controversial topic, but the corollary to such an idea is the title of this post. Competency-based education does not objectively measure learning as a constant, for there are facet of learning that cannot be measure under any circumstances.
The importance of sexual education is to teach about three key ideas: "What is Consent?", "What are Sexual Transmitted Disease?", and "How do people deal with the consequences?". Too many extreme right-wing wishes for sexual education to teach exclusively about abstinence instead of the most important key to sexual education, the first key point, "What is Consent?".
"Pressuring to Consent"
Coercion is a form of force, and constantly asking for sex until the other party feels so frustrated that they say yes is not consider giving consent even with the word yes. Only yes with the correct tone and mental state can be considered consent.
What does all of this have to do with "Learning as the Constant and Time as the Variable" ? All, but sexual education is a topic that students will all need to learn, and age of consent is a time variable where those that mastered "sexual education" should be able to give consent, and hence, age of consent is the variable.
The corollary to "Learning as the Constant and Time as the Variable" is to drop the statutory rape laws, but society will not allow that. Therefore Time is the Constant, and Learning is the Variable.
As a side note:
The definition of forcible rape has not be re-written into sexual neutral (politically correct) terms in 2012:
"Forcible rape, as defined in the FBI’s Uniform Crime Reporting (UCR) Program, is the carnal knowledge of a female forcibly and against her will. Attempts or assaults to commit rape by force or threat of force are also included; however, statutory rape (without force) and other sex offenses are excluded."
"The revised UCR definition of rape is: Penetration, no matter how
slight, of the vagina or anus with any body part or object, or oral
penetration by a sex organ of another person, without the consent of the
victim. Attempts or assaults to commit rape are also included; however,
statutory rape and incest are excluded."
By the law before 2013, males cannot be rape victim, but they may be "sexual assault" victim.
