The witch hunts were sometimes endorsed/supported by the authorities, and other times not, just like the Red Guards:
Under Charlemagne, for example, Christians who practiced witchcraft were enslaved by the Church, while those who worshiped the Devil (Germanic gods) were killed outright.
By early 1967 Red Guard units were overthrowing existing party authorities in towns, cities, and entire provinces. These units soon began fighting among themselves, however, as various factions vied for power amidst each one’s claims that it was the true representative of Maoist thought. The Red Guards’ increasing factionalism and their total disruption of industrial production and of Chinese urban life caused the government in 1967–68 to urge the Red Guards to retire into the countryside. The Chinese military was called in to restore order throughout the country, and from this point the Red Guard movement gradually subsided.
I would say the most relevant difference between them is that witch hunts were more “organic”, in other words they happened pretty much everywhere where people believed in the possibility of witches (which was pretty much everywhere period), whereas the Cultural Revolution was driven/enabled entirely by ideology indoctrinated by schools, universities, and mass media propaganda.
