I know Marx was German, but Communism took hold first in Russia. The Russians have given us this sick philosophy as well as political correctness, diversity and other obnoxious beliefs. THEY are to blame for much of the world’s problems, period.
Marx was German and the first Marxist inspired party was the German SPD which was founded as a Marxist political party. It is the second leading party to this day having only recently lost their majority status.
The US also bought into this philosophy early on in its inception but it has taken until now for the Marxist to get the upper hand. Unfortunately, while most other countries are disavowing Marxism we are embracing it.
In the US we had Progressivism and Social Darwinism well before the 1900’s. These philosophies are kith and kin to Marxism and it blinded many in this country to the evil that was occuring in Russia.
