To be honest, at this point, I'm not sure it can be -- I've been harping on this for 20 flipping years, never got anywhere, and there, for a brief shining moment 4 years ago, it looked like there might be enough broad range momentum to curb the tide. Now, I don't know. I think trying to stop it is now a bit too little, too late, and too misdirected.

PS. and I'm really going to shit on everyone's parade: the state/federal departments of education not only set the curriculum; they select the texts and products...including what you can find online (for all the homeschoolers out there; be careful!), including private/charter schools -- who do you think accredits them?

The problem is that there are parents who are quite cool with this -- so they send their kids to progressive private schools and they get involved in the local public school boards and pta and push for all of this shit because you know, they care so much. And they're backed by state and federal gov. if not local (although sometimes all three), as well as all the "non-partisan" local political apparatus (which are all connected to state and national very political apparatus). And then when shit does happen, the people don't go after them...they go after the teachers and school administration, which can be a really mixed bag -- not everybody working there likes the progressives, but... (as a former one, I did throw in the towel...to be conservative and teacher is to stick one's neck out...and still get shit on by your own "side" -- I do rather understand other groups in this regard, like cops).

If you have kids -- really check out your kids' schools (some public ones are still better than some charter); and if you home school better check what's allowed (yes, allowed -- it's not going to last for long). Go underground (my kids' reading lists at home are a lot more diverse and advanced than what the school provides, always has been, and we're in a pretty good district -- we made sure of that).
