Whose responsibility is it? If someone is debating an issue I would hope they are familiar with and understand the underlying statistics relevant to their claims. If they claim conclusion X based on statistics Y but omit (intentionally or out of ignorance) that conclusion P is also plausible based on statistics Q, it is the responsibility of anyone aware of statistics Q to inform those claiming conclusion X that X isn't the only plausible conclusion one can arrive at because statistics Q exists that suggests conclusion P.
Are you seriously suggesting that someone aware of a different dataset that supports a different conclusion only bring attention to that dataset if those claiming the original conclusion are interested? That's preposterous.
