Columbus wasn't the first person to step foot on American soil, but he did discover America for Europe, which is the origin of this country and most others in this land. Without him, Enlightnment Era Liberals would have had no place to establish the American Experiment.
Black people didn't exclusively enslave themselves, and no teacher claims that and gets away with it with left or right leaning parents. WE ALL HATE SLAVERY YOU LYING F*CKTARD!
The critical race theory we don't want in classrooms is the idea that white people alive today hold blame for the bad that their ancestors committed, and it requires them to nearly worship at the feet of black people in order to be a proper "antiracist." Officially, "Critical race theory" was a social and legal theory founded by Derrick Bell, and every intricacy isn't taught in kindergarten classrooms. What is taught in some areas, which red states are rightfully banning, are dumbed down versions of it. They encourage racial solidarity, where Black, Mexican, or Native band together with themselves and make the "oppressive white kids" know how much they are held down by their existence. They teach the false ideas of the 1619 project, which the New York Times quietly edited to make it pass fact checks after it had done the damage. They teach that America was founded not on the principle of a representative government where nobody holds absolute power, but only to keep down black and native people. If that was true, Slavery could have never been abolished and reservations couldn't exist! They teach the works of race hustlers like Ibram X Kendi. THIS is what we stand against being taught in the classroom. Read one of those "Anti CRT" bills that have passed in red states and you'll see the teachings of MLK codified into law. I DARE YOU TO GO READ THEM!
