It would have taken you two minutes of investigation to realize that these books are nothing like To Kill a Mockingbird. You could have read the SPLC article that the author linked, which lists numerous books explicitly promoting white supremacy, violence against minorities, and ultimately the extermination of anyone who isn't white. Or you could've just looked up the books' summaries and a few choice quotes to see how overtly racist they are.

From Mein Kampf:

> The Jews were responsible for bringing Negroes into the Rhineland, with the ultimate idea of bastardizing the white race which they hate and thus lowering its cultural and political level so that the Jew might dominate. For as long as a people remain racially pure and are conscious of the treasure of their blood, they can never be overcome by the Jew. Never in this world can the Jew become master of any people except a bastardized people.

From the Turner Diaries, in an extended passage describing the author's extermination fantasy, much of which is too grotesque to even share:

> There are many thousands of hanging female corpses like that in this city tonight, all wearing identical placards around their necks. They are the White women who were married to or living with Blacks, with Jews, or with other non-White males. There are also a number of men wearing the I-defiled-my-race placard, but the women easily outnumber them seven or eight to one. On the other hand, about ninety per cent of the corpses with the I-betrayed-my-race placards are men, and overall the sexes seem to be roughly balanced.
