Revelations of radical activism by a teacher in California with an Antifa flag in his classroom and marking student’s papers using stamps with images of communist leaders roiled Sacramento area parents. In a shocking and at times profane 12 minute video, Inderkum High School AP Government teacher Gabriel Gipe explained that he has “180 days to turn [students] into revolutionaries.” When a student anonymously complained about the Antifa flag in his classroom, Comrade Gipe admonished his students by explaining that the flag “is meant to make fascists feel uncomfortable, so if you feel uncomfortable, I don’t really know what to tell you. Maybe you shouldn’t be aligning with the values that this [Antifa flag] is antithetical to.”

While this example is shocking, it comes as no surprise. As we outline in our new publication, A Concerned Citizen’s Guide to Engaging with Public Schools, civics and history as academic subjects are under assault by left-wing political operations that masquerade as education policy organizations. Progressive thinking is so pervasive in our nation’s colleges and universities that it has seeped down to our elementary, middle, and high schools. Programs and resources like the Southern Poverty Law Center’s Teaching Tolerance/Learning for Justice, the New York Times and Pulitzer Center’s 1619 Project, Black Lives Matter at School, and the Zinn Project are far too ideological to be used as resources in public schools.

And yet, it is much easier to find those materials in your local public school than it is to find resources that honor America’s founding documents, our nation’s founders, and the important rights guaranteed by the First Amendment, including religious freedom. Programs like 1776 Unites (a project of the Woodson Center), the Hillsdale 1776 Curriculum, and the Bill of Rights Institute provide resources that educate students about the promise of America without ignoring difficult topics like slavery and segregation.

As we documented in our publication The SPLC’s Teaching Tolerance, an organized incursion into schools has been underway for decades. Efforts to influence and indoctrinate future teachers during their college years seem to be paying off for progressives. This is why parents and concerned citizens must act to engage public school systems to demand accountability and educational excellence—without political agendas. Radical progressive ideology has become so normalized in educational spaces that extreme content is no longer recognized as controversial. Teachers like Comrade Gipe can harangue students and turn them into political agitators, and it all seems completely normal to his coworkers and students. Clearly, Christian witness is needed urgently in our nation’s schools.

Pray about this and prepare to engage. Discuss these issues with your family and friends. Be unafraid to share the solutions to these problems that Christ’s love and the gospels offer. If you are a parent, meet each of your children’s teachers and make sure your children talk to you about their assignments and school activities. For those able to be more engaged, attend local school board meetings and take notes. Run for your local school board so that common sense can prevail over the one-sided thinking in place now. We live in the greatest nation on earth, the beacon of hope for the world. Let’s make America’s school systems as exceptional as our nation. Our children, entrusted to us by God, deserve our very best.
