The Wikipedia page for Birth Control says that the rhythm method has a success rate of 76% in typical use, 95%-99.7% in perfect use. rtc claims that the source for the upper figure describes only a specific combination of techniques called the symptothermal method, and the upper figure should be 97%. Doc James disagreed about the interpretation of the source.

So rtc is arguing that the rythym method is not as reliable as Wikipedia claims that it is. JzG saw that the discussion was about the rythym method and jumped in to accuse rtc of bad faith and ridicule what JzG assumed to be rtc's Catholic religion.
> This is pretty pointless. It seems to me, as an outsider, that the intent is to obscure the fact that Vatican Roulette does not work, and is supported as a form of birth control only by religious groups, for that reason. Guy (Help!) 00:34, 20 December 2017 (UTC)
rtc is confused by JzG's reaction and clarifies his position of what he thinks the source says. JzG then reported rtc to to ANI.

> Context: "fertility awareness methods" of birth control are advocated almost exclusively by religious groups, as they have a high failure rate. User rtc is trying to include special pleading about how they are really not a lottery after all as long as you use multiple techniques. So far he has tried edit warring, condescension[19] and WP:POINTy tagging[20][21]. Numerous other editors are reverting the changes, including Doc James, who I think we're all aware is medically qualified. I think a topic ban is needed. Guy (Help!) 08:36, 20 December 2017 (UTC)
After rtc reveals himself to be nonreligous, and no one on Wikipedia should be forced into revealing their religious beliefs or lack thereof, BaseballBugs and Nagualdesign ridiculed rtc for Catholicism. JzG called for rtc to be topic banned from birth control, gaining the support of Beyond My Ken, Jytdog, Mjollnirpants, Roxy the dog, SarekOfVulcan, David Eppstein, Marianna251, Flyer22 Reborn, and Only in death does duty end.
fish&karate, GreenMeansGo, Cjhard, and Tornado chaser opposed sanctions because the ANI was made in bad faith, was full of false charges, and included little to no evidence of misconduct by rtc. rtc gained no support for a proposal to warn JzG against making false claims and blocking someone with whom they are in a content dispute.
