Turning Point USA is an American conservative, right-wing nonprofit organization whose stated mission is “to educate students about true free market values.” It was founded by conservative activist Charlie Kirk, who recently published the tweet shown.
Others have responded more powerfully and directly with tweets of their own. But since my FB timeline is essentially a Sunday School class where I ought not swear, I will only say the following.
My dear Mr. Kirk, you should tell the truth as it happened and has been recorded by real historians: Our culture began with genocide and was built on slavery. American nationalism that thinks we are the most exceptional people on earth is silly and nothing more than fake news.
