It seems that the material destroyed at the Institute for Sexual Science is precisely the sort of stuff that the Trump regime wishes to supress. So any LGBT research and information.
Basically anything that the Nazis banned. The list here still seems relevant. Transpose 'German' for 'American':
All of these types of literature, as described by the Nazis, were to be banned:
- The works of traitors, emigrants and authors from foreign countries who believe they can attack and denigrate the new Germany (H. G. Wells, Romain Rolland);
- The literature of Marxism, Communism and Bolshevism;
- Pacifist literature;
- Literature with liberal, democratic tendencies and attitudes, and writings supporting the Weimar Republic (Walther Rathenau, Heinrich Mann, Thomas Mann);
- All historical writings whose purpose is to denigrate the origin, the spirit and the culture of the German Volk, or to dissolve the racial and structural order of the Volk, or that denies the force and importance of leading historical figures in favor of egalitarianism and the masses, and which seeks to drag them through the mud (Emil Ludwig); Books that advocate "art" which is decadent, bloodless, or purely constructivist (George Grosz, Otto Dix, Bauhaus, Felix Mendelssohn);
- Writings on sexuality and sexual education which serve the egocentric pleasure of the individual and thus, completely destroy the principles of race and Volk (Magnus Hirschfeld);
- The decadent, destructive and Volk-damaging writings of "Asphalt and Civilization" literati: (Oskar Maria Graf, Heinrich Mann, Stefan Zweig, Jakob Wassermann, Franz Blei);
- Literature by Jewish authors, regardless of the field;
- Popular entertainment literature that depicts life and life's goals in a superficial, unrealistic and sickly sweet manner, based on a bourgeois or upper class view of life;
- Patriotic kitsch in literature.
- Pornography and explicit literature
- All books degrading German purity.
I guess books that have been banned in US school libraries over the last few years too.
And finally, any political material that is antithetical to the far right.
Have you taken a look at Project 2025 and half the crap that Trump has said he's going to do?
