Montessori Schools?

Growing up I knew many kids who had attended Montessori schools for nursery school and kindergarten, and most turned out to be excellent students, but sometimes socializing took a back seat, to such an extent that a few needed to transfer out of public school in my town. There seemed to be benefits to it, but there were definite drawbacks.
My roommate is a teacher at an afterschool Montessori school near the waterfront. Having worked with these kids for quite sometime, she hopes to send her future children to Montessori school. Shocked by this, because of my own background with students going through the program, I asked why. She reminded me of the infinite benefits that particularly creative children can gain in such an environment, with offerings in the arts, drama, and creative play. I could see that being true in some respect, but the pure and simple fact that a teacher isn't allowed to use the word "kids" in reference to his or her students, made me question the whole thing.
Censorship in the classroom is exceptable to an extent, but restricting words, besides the obvious profanities, I think is ridiculous. This sets students up for failure should they ever leave this environment, and they inevitably will. Putting a child in a bubble doesn't teach them enough.
Perhaps I only feel this way because of the way I was raised, where learning from experience and other's experience was held with the utmost respect. To censor a child or what they hear means they aren't exposed to it in the classroom at first but when they get older they will inevitably hear it. So what's the point of building a fantasy world for a couple years of a child's life, only for them to be exposed to reality in a short amount of time?
