PragerU CEO Marissa Streit has warned that some teacher training programmes are promoting the concept of "adultism" – framing adult and parental authority over children as a form of oppression – as part of a broader push to embed contested social and political theories in classrooms. Speaking to Fox News Digital, Streit argues this trend, tied to the spread of "ethnic studies" curricula, risks undermining trust between parents and children and is being introduced into schools without adequate scrutiny or parental input.

Streit contends that framing that casts parental authority as inherently oppressive originates from ideologically driven activists and amounts to importing a Marxist-inflected worldview into American education. She cites the growth of ethnic studies programmes as a vehicle for these ideas, suggesting they are being embedded in professional development materials used to train teachers nationally, though the article does not cite specific data on how widely such training has spread.
