Walking it back is going to be very difficult. We have an entire generation of teachers that are passionate believers in gender ideology, and school boards that back them up.

The only possibility I see is complete defunding of the public schools. Go entirely to a voucher system and private schools. This will at least give parents a choice. Most will just choose the cheapest, which will be staffed by all the gender ideologues who can't get jobs at the better schools, but it's something.
