That is a misreading of the article and of the survey results. Here, I'll help you spot the sentence most pertinent to the headline: "Other findings include the fact that only a third (31 percent) of the Biden voters said they are active in a local church congregation." (It appears that they don't even attend church services.) Hence the article's conclusion that 59% (more than half, not quite "two-thirds," but "most") don't practice their religion. However, Barna is not the one who came up with the headline or the article, so the statement, "according to George Barna, disciples of Jesus Christ must... (blah blah blah)" is a distortion and an inaccurate attribution. Really, it escapes me why anyone would wish to belittle someone who conducts a survey (Barna) and tells the results thereof. Or with a journalist who writes up a news story about the survey, either. Perhaps the newspaper editor who picked a headline to fit available space could have been more precise with his wording, but is it worth a rant?
