"And if teenagers want to read about the sex lives of plants, more power to them!"
You clearly don't understand. The mere mention of reproduction, even in plants, sends teenagers into a frenzy of lust. That's why we no longer teach about the birds and the bees, you see. All that egg-laying and pollinating going on inflames adolescents and causes them to engage in wild orgies of sexual licentiousness.
Why, the simplest things can trigger this sort of immoral behavior in teens. A case in a city (unnamed for privacy's sake) occurred when a wind blew through the schoolgrounds. Budget cuts had prevented the lawns on campus from being mowed frequently, and the wind blew the seeds from all the dandelions on the campus all over the place. Within minutes, the students had all removed their clothing and were rutting mindlessly on the grass.
You can see how serious this all is, I'm sure.
Good point, I'm chastened at my lack of understanding of the seriousness of this problem. By all means, let's continue restricting such licentious inflammatory knowledge. Who cares if China and India take the lead in science, we'll have all the pure teenagers, their heads uncluttered by knowledge of plant reproduction!
