At school the fourth grade boys, including Gerald and Randy's sons, Kyle Broflovski and Stan Marsh, discuss the witch, whom they assume is female.
When Randy and his friends discover that Sentinel Hill has been closed off to the public, this confirms their perception that they are being persecuted for Duncan's actions in a manner akin to a witch hunt, though their avoidance of that term recurs as a running gag throughout the episode.
At a school assembly the following day, Randy and his witch-garbed friends put on a musical number intended to convey the public service message that not all witches kidnap children, but merely the one bad one.
Stephen is lured to a Ross Dress for Less parking lot, where they publicly accuse him in front of shoppers and the police of being the bad witch, but Chip descends before them on his broomstick.
Jesse Schedeen of IGN rated the episode an 8.3 out of 10, summarizing his review with "South Park continues to establish a winning formula this season, focusing on more standalone storylines that still pull from current headlines in clever ways.
"[2] Charles Bramesco of Vulture rated the episode with one out of five stars, stating in his review "The one thing South Park won't do is take a side, insulating itself from criticism by hiding behind the 'equal-opportunity offender' line.
Club gave the episode a B+ rating, stating in his review, "'Sons a Witches' rightfully calls out that sort of self-righteous hypocrisy—the people who view themselves as different from the Harvey Weinsteins of the world, when in reality, they've taken advantage of the same gross power imbalance in Hollywood and elsewhere.
While getting loaded and smoking crack in the woods may be a crass metaphor for the systematic nature of toxic masculinity, it fits right into South Park's wheelhouse of symbolism.
