The one that by policy tortured heretics, burnt witches, made no technological advancements save armor and weapons between about the time of Heron of Alexandria and Copernicus, fought with Muslims because they thought God wanted them to, conducted an Inquisition, believed Jews were demonic, and thought the Earth was at the center of the universe.
Most of this I don't think really has to be addressed (because it's more or less true, even though the way in which you're presenting it indicates a perhaps shaky understanding of the context behind why these things were the case and even though you're unduly dismissive of what medieval society was able to accomplish in its less savory aspects' despite), but the bolded part is completely false and ridiculous.
Yeah, if you think there weren't any technological advancements in Europe between "Heron" and Copernicus, you're pretty much a complete unreconstructed ignoramus about history. An extremely partial and non-chronological list I can come up with off the top of my head: blast furnaces and forged steel, stirrups and horseshoes, soap, firearms, crop rotation, heavy plows, enclosure, flying buttresses and pointed arches, sailing ships, magnetic compasses and astrolabes, the rudder, glass-blowing, mechanical clocks, windmills, paper, the printing press, eyeglasses, beer, wells, universities, the scientific method, and fwucking magnets (how do they work?).
Most Indians who live outside reservations are every bit as affluent and successful as their white neighbors. It's actually pretty much the best real-world example of the "culture of dependency" rhetoric.
*Ahem* Native Americans
Ah, I used to always use that term, but an Indian friend of mine informed me that only white people use that term and he and most others prefer the term "Indian." I did some searching around and apparently that's true. I therefore changed my terminology.
