The submitter of this story inserted 'rationalist' into the title; it's not in the headline and IMO it's calumny. Would you take it back out?
Perhaps you would also describe the Manson family as a Christian death cult.
Edit: I think "death cult" is linkbaity though, so I replaced it with "Zizians". I hope that's neutral enough for everybody because I'll be offline soon.
(Replacing a general-sensational term with a proper noun is often a good debaiting trick.)
Neat term, debaiting -- though I misread it for a moment.
