"My friends and I are being described as like Satan’s lapdogs, the devil and the Manson family all rolled into one."

Wrote Michelle Zajko, in a letter from jail, quoted in The London Times, which looks like this:

 

Note the caption — The Times doesn't seem to know the difference between "peddle" and "pedal." Imagine riding lies around like they're some kind of bicycle!

As for these Zizians:

The Zizians have been described by authorities as an “extremist group”. A woman who knew one of their alleged members described them as a group of “highly intelligent, transgender, vegan” individuals. Social media posts attributed to the group have mentioned “evil people ganging up to kill off good people”, and a wish to “strip society of morality”....

About that figurative use of "lapdogs," the OED finds it first in the 1838 novel by Edward Bulwer-Lytton novel "Alice, or The Mysteries," where a character says:

"I allow that your beauty and talent were sufficient of themselves to charm a wiser man than Doltimore; but had I not suppressed jealousy, sacrificed love, had I dropped a hint to your liege lord,--nay, had I not fed his lap-dog vanity by all the cream and sugar of flattering falsehoods,--you would be Caroline Merton still!"

Now, that's writing! Perhaps you remember The Bulwer-Lytton Fiction Contest, which "challenged entrants to compose opening sentences to the worst of all possible novels."
