Would you say Lutheranism and the Theology of Liberation are equally as problematic as the KKK and Nazis?

Not as bad, but for example Sweden is and Prussia was lutheran, it's also religion of majority of Germany so majority of nazis were also lutheran, Bismarck and his kulturkampf too. Liberation thology is also better than mainstream catholicism but it's still toothless class collaboration ideology that deradicalizes people, a kind of religious socialdemocracy.
