Upon reading the comments by a Kensington parent, Barbara Ruppert, in reference to the sex education debate in Montgomery schools {Metro, Sept. 25}, I am concerned that her opinions could affect the quality and quantity of information given to our children. This parent, in opposing sex education aids in public schools, has likened the educational classes to learning how to drive a car. To quote Barbara Ruppert, "You don't sit a youngster down behind the wheel of car, show him how to drive, hand him the key, and then say, 'Don't drive yet.' "

When something happens in our society that causes us concern we use what I term the "inform and warn" technique. We warn our children of the dangers of drug abuse, drinking, driving while intoxicated. We tell them not to get involved in such activities and, if they already are, where they can get help. Then what about the dangers of sex (i.e., pregnancy, veneral diseases, etc.)? If they are already involved in sex, they need to protect themselves.

As far as how long we would like our children to wait before engaging in sexual activity, I believe that discussion is best left to parents' discretion. Parents, talk to your children. Tell them how you feel about it. Then listen to how they feel. They are the silent majority in all of this.

We are teaching our children in public schools how to balance checkbooks, how to type, how to cook and, yes, how to drive. They're not allowed to have a checking account, but it's information for when they do get one. Schools are teaching them how to work on cars, not because they own one, but because they probably will in the future.

Most parents know that what is denied to children becomes coveted by them. Take sex out of the closet and treat the whole subject as normal "adult" behavior. Our children are learning how to become adults every day. We must stop hiding our sexuality and strive to provide our children with as much information about this subject as we can possibly give them. What exactly are some parents afraid of?
