For whatever it’s worth, I’m an advocate of Montessori and I’m not left wing in the slightest. The things I like most about the Montessori approach are the focus on fostering independence at a young age and (some) freedom to focus on what the student is interested in.

I don’t think of either of those concepts as mapping particularly well to any left-wing ideology I’m familiar with except, perhaps, the back-to-the-land hippie movement.

Contrary to some of the BS in this thread, the kids do, in fact, learn to read and do math.

Your comment is nonsensical. Montessori isn't partisan anymore than algebra is.
