Bwahahaha. :-D I still remember how we used to innocently study such stories when we were kids without knowing the second meaning of it. As adults we are now far more knowledgeable. That means we have so many options to choose from. We can select any meaning which we like. :-D And that's always the one which is controversial in nature.
You are absolutely right @ruth-girl that these are not for the kids. Their minds should get nurtured from the basic level. There is a time for everything that should happen in a particular order. Hope this be followed. :-)
I never came across such readings in my childhood, I evolved into an insane woman by reading "harmless" stories :P
But that does not mean we should have little ones read such stuff...
