I’m not intimately familiar with all of the details of what is being advocated in California. All I can speak to is my perspective on what equity is and how I think it should be applied.
People who disagree with the basic concepts around equity tend to view the entire discourse as a monolith, but people are actually allowed to have different opinions on what is actually equitable and what isn’t.
Personally I wouldn’t support doing away with advanced math courses either. But just because someone does that in the name of equity, doesn’t mean I think equity itself is bad. I’m able to separate the two.
