Over the last decade or so the home school movement I witnessed in Texas came from the fundamentalist right. They did not want their kids being taught evolution in science class and insisted on school prayer. Cooperatives were formed to provide mutual support to home schooling parents who were mostly moms. And, here still exists a strong voice for school vouchers to allow public school funds to be diverted to religious schools. Public schools are already strapped for funds and these die-hards want to take more from the coffers and give tax dollars to church run schools. This selfish attitude is not explainable.
The fundamentalists have infiltrated school boards and state offices to change the actual curriculum and authorized books used in class rooms. They have won this battle at many levels of education in red states.
Most recently, liberals have chosen home schooling, understandably, in an effort to keep their kids away from this far right agenda. In many school districts the revenue stream is based on "butts in the seat" so schools lose if the right or left take kids from the classroom to home schools. Both groups want to be exempt from paying school bond taxes since neither use public schools.
There may be no short term solution for the average school. Parents search hard for magnet schools and for the ones who can pay for private schools. Our public school will suffer until we vote ideology and religion out of the classroom.
