Critical race theory is the hottest topic on Fox News. And it’s only getting hotter, writes Jeremy Barr. “The concept has been around for more than 40 years, according to EducationWeek, but it has become a major programming theme on Fox News only in recent months as parents, buoyed by conservative activists and groups, have vocally opposed the teaching of the theory — or something similar to it — in schools throughout the country. Republican-led state legislatures have voted to outlaw it,” our colleague writes. “The term ‘critical race theory’ was mentioned just 132 times on Fox News shows in 2020. In 2021, it has been mentioned 1,860 times, according to a tally using the media monitoring service Critical Mention.”
