I am totally on your side in this issue. There has a distinction to be made between free speech outside of a place like a school and according to American free speech she is totally allowed to spill this bullshit without fearing any penalization. But at the point where she admits to teach her own beliefs to children, especially when those aren't in line with what is acceptable in a public school space and what is required from teachers to teach, indoctrinating them, there has to be punishment and, more importantly, protection for the children.
I'd personally even go further as to taking her beliefs that she so openly advocates as reason enough to at least investigate how this might affect her teachings, though it should be strictly about her teachings and not her personal beliefs.
