You and I do not get a vote on what the state of Florida does with its educational system, or whether California is correct that math is racially biased and shouldnt include calculus teaching. The voters who live there determine that. I understand you may neither like nor trust them, but that is the premise upon how we are governed, by representatives we elect. Majority rule generally, with protections for core rights of some types of recognised minorities ( which are not at issue here).
Neither liberals nor conservatives count as constitutionally protected groups. Within very broad parameters, states run their own education systems. The federal govt can set conditions on helping to fund those systems or students therein, again subject to both 1) national elections and 2) broad constitutional requirements.
