Conservative activists and politicians have condemned critical race theory and have supported measures to prohibit teaching the subject in public schools. The anti-critical race theory movement is part of broader social movement activity inspired by the 2020 presidential election. Many conservatives view Donald Trump's defeat as a victory for antiracism. In response, they have portrayed the election as a product of fraud, enacted laws that will make it more difficult for people of color to vote, endorsed measures that would chill antiracist political activism, and banned instruction related to contemporary antiracist theory. These practices have been employed historically in response to antiracism. This history should guide social justice advocates as they analyze the meaning of countermovement activity and build strategies of resistance.
