Well..to be correct, it labeled several alleged parental groups..whose actions thus far merit the label. The SPLC has had its growing pains, and of course, it has had to weather the constant storm. All in all...they make the right call, most of the time. I can usually tell by the volume of the opposition whining.
From the OP:
The Southern Poverty Law Center (SPLC) sparked a firestorm this week after it added several prominent parental rights groups to its annual "Hate and Extremism" report, including Parents Defending Education and Moms for Liberty, describing them as "hard-right" and "reactionary anti-student inclusion groups."
According to the new SPLC report, schools "have been on the receiving end of ramped-up and coordinated hard-right attacks."
After being "spurred by the right-wing backlash to COVID-19 public safety measures," parental rights groups appeared to have "grown into an anti-student inclusion movement that targets any inclusive curriculum that contains discussions of race, discrimination and LGBTQ identities," according to the SPLC, which has tax-exempt status from the IRS.
"Like many other hard-right groups, these reactionary anti-student inclusion groups are constantly painting themselves as an oppressed class, while vilifying those discriminated against," the SPLC added.
