At the beginning of the year (here in the US) I had to sign a waver allowing the school nurse to give my kids Tylenol and Motrin. Why isn't the school required to notify parents before dispensing a much more serious drug??
The only answer that I can think of is, essentially, politics. Because they are pushing an agenda of "free sex for all with no consequences" they have gone out of their way to hide it from the parents to begin with, and so notifying them of side effects would have interfered with their primary goal, which is not "women's reproductive health" as they say but in promoting this "no consequences" agenda to children. If a few children die or are hurt with lifelong consequences from these pills, (aside from the profound pain that they will most likely feel later in life, knowing that they have murdered their own child) in the minds of the school administrators and activists that is a small price to pay for pushing their agenda.
It's absolutely sickening and makes me terribly, terribly sad.
