Everything listed there are common things considered "racist" by media and activists. I can support my argument with many links, if needed.
Again, they're intellectually dishonest. They're overly simplistic and twisted to the point of absurdity. No one thinks standardized testing is racist.
Some believe that the construction of the test, the phrasing, the material, the format, etc. is geared more toward what is familiar and taught to a particular section of students and therefore sometimes yields inaccurate results.
But that's a complex, nuanced discussion that isn't going to go anywhere on the internet with someone who boils it down to "standardized tests are racist." It's the converse of what Carter's mom tried to do. One bothers you, one is "factual."
Just not the time or place for it. You guys have fun until it gets locked or moved.
