The problem I have with the posted article is the eye-catching, all-inclusive phrase "The Cancer Virus", as though there exists a single virus that causes all cancers. That click-bait assertion is clearly false, and such phrasing invites objection, no differently from a thousand click-bait ads at the bottom of a Daily Mail or similar tabloid webpage.
