Well maybe I'm wierd, but here goes...
I am of the belief that parents should educate , and be involved in the education of children. I also believe children have rights too, I don't recall the Constitution stating one has to reach a certain age before one's rights kick in. I was raised where I could go to my parents to seek answers to questions, regardless of the subject. This extended to immediate family (uncles for example) and some "elders" ( preacher, adult friends of the family, church members, neighbors). My parents and these other persons had /shared what and the how the way my parents wanted me raised (sibs too).
Telling a kid "don't" is a sure way to get a kid to "do". I was encouraged to read, ask questions. I could even do this with teachers,and this was a time with a war going on, assassinations, and racial tensions. Controversial books and topics were discussed and brought out in the open. Kids are gonna seek and wonder,why not be responsible and educate them,instead of a "stranger" educating them.
No, I haven't sired any kids of my own. I did raise 3 sibs. I did have a stepson many years ago. His mom and I were in accordance with this. Any time my sibs or stepson had a question about anything they read or were curious about, I answered. I feel perhaps sometimes some questions may be better answered by a certain gender, then again I never ( or when married) we never put a "wall" up.
Best example : my wife was a nurse, when her son and neice had questions about guns, sex, condoms and tampax we sat them down. I gave the gun safety lesson and answered questions. My wife used a bananna to give the condom demonstration, I used a cantaloupe I anatomatically altered to give the tampax demonstration. The kids sat side by side ( not sequestered like in gym class). We wanted to show and demonstrate it is the responsible parent/adult that teaches. In the real world they would encounter these questions. We felt by doing this, this way, was best. Better than schoolyard scuttlebutt, mis-information, embarrassement later in real life...or getting into trouble. Yep they got a bit red-faced, but you know these kids knew anytime they needed a questions answered they could come to us.
They read "banned books" , questions asked and answered, honest and at a level of their understanding.I/ We encouraged this.
Of course SIL did get real red when daughter came home with condoms...explained to her mom how they worked. *g*
