@His4Life:
I see that you still need to work on your reading comprehension.
This is true, though. What belief systems have atheists come up with besides homosexuality and socialism/communism?
1. The OP is about “systems of morality”, not about belief systems.
2. Many commenters provided possible explanations for the development of moral systems without a god, so “this” (i.e. the OP) is not true.
3. Homosexuality, socialism and communism are not belief systems, they are a sexual orientation and political ideologies, respectively.
Nazism and the KKK are occult movements, not Christian movements.
1. Goomy pls did not call them Christian movements.
2. National Socialism was not an “occult movement”, it was a political ideology, namely a form of fascism.*
3. The Klan was founded by Protestants and targeted Catholics and Jews, beside Blacks and later became influenced by the Christian Identity thing.
And I notice that you ignored all the other things Gloomy pls did mention.
*Some members of the party may be into the occult, but that does not necessarily mean that all Nazis were or even that the majority of them knew about it.
