This week, all four of our winning comments come from our post about a ridiculous column arguing that fact checking is an assault on free speech. In first place on the insightful side, it's an anonymous response to the question of whether we needed fact checking to help turn people against slavery:

There were hundreds of "scientific" theories of racism which have been used to support the "natural" inferiority of various races in support of slavery. Physical anthropology, craniometry, anthropometry... dating at least back to the polygenism of the enlightenment (though to be fair, polygenism was a legitimate query at the time). And as each of these was eventually "fact checked" and found wanting, more were created to replace them.
