No less than the Bangkok Post in Thailand is reporting on birther nuttiness in a new article, "Bias, by any other name, still blinds you to the facts.”
In the US, some 45% of Republicans believe that Barack Obama (a Democrat) was born overseas and thus ineligible to be president. This isn’t for want of information. The press has reported extensively on the issue, pointing to contemporary birth notices in Hawaiian newspapers and to his birth certificate, now available online.
But facts don’t matter to the "birthers". It is just that they don’t like Mr Obama (as a Democrat, as an African American, as a liberal, etc) and they are not prepared to listen to any positive information.
