A Jan. 5 NewsBusters post by Tom Blumer once again insists that the recent decline in Ford sales can only be attributed to a boycott of its products pushed by the American Family Association for, in Blumer's words, "it's [sic] slavish devotion to politically correct causes" (read: it markets cars to homosexuals). It's a meme he's pushed before.
But also as he's done before, Blumer offers no hard evidence of a correlation between the boycott and Ford sales, only an estimate that "the AFA boycott is impacting the buying decisions of 15-20 million adults making up at least 10% of the potential market" -- and that estimate is based on other estimates for which he lacks hard evidence as well. Blumer offers little analysis of overall auto sales to support his claim; all he has is the circumstantial evidence that Ford's sales have dropped more than other automakers and no indication he has examined other factors that impact auto sales.
Further, Blumer offers no explanation why he or the AFA find marketing cars (or anything else) to gays to be so offensive.
