Yes and pre-school. And no, I wouldn't freak out over something like this because before I ran crying to the media, I start with a conversation with the school as to their "why". And even if I didn't agree with them, I'd still be fine because hiding my kid from opinions that contradict mine isn't my parenting philosophy. My personal philosophy is that everything is a teaching opportunity. So, if I don't agree with the school's direction (which surprisingly is happening at the pre-school age), I just teach why I don't agree and I teach why the school is doing what it's doing.
My kid should know that he will encounter opinions that contradict that of his father and he should be armed with explanations for why he doesn't have to accept them...but he still has to learn/understand them.
