Carlson exaggerates, but not as much as this article.

It is not "white natinalism" or any other form of racism to decry the dangers of Critical Race Theory. CRT is a marxism derived attack on America, not just on whites, but on the entire idea of America as a nation based on merit, as a nation. based on what you do rather than who you are or the color of your skin.

EIther the author supports this radicalization, meanwhile projecting "radicalization" onto the right, or the author is terribly uninformed. But then, the phrase "dog whistle" has long been used to accuse conservativess of racism when the accuser cannot find any actual racism on the part of the accused. It is standard leftist tripe.
