You don’t like that the school is teaching that capitalism is wrong? Do the capitalist thing and vote with your wallet, send your kids somewhere else. If you don’t like that the school is teaching that racism is a problem, then find a school where that isn’t an emphasis. I strongly suspect (based on me knowing how these articles get written and how parents groups misinterpret everything) that the racism curriculum is exaggerated in this article anyway. But regardless, if you don’t like the elite curriculum in California and New York, there are 48 other states you could move to and find a good school. I’m sure some states have fine institutions of learning without all that progressive nonsense, if you could be bothered to disgrace yourself and move there.
Edit, rather than making another comment: and maybe it’s a good thing the school is indirectly teaching kids to shut their mouths and not share a viewpoint that they know is unpopular. I share my opinion freely on the internet but at work I have to pick and choose what I say about our projects. This is good education.
