Those idiots actually believe socialism would eliminate scarcity? In what socialist-Communist country has that ever been true?! Shelves empty of desired consumer goods was a constant part of life in the USSR. Many of the famines and mass starvations of the 20th and 21st Centuries were government-caused ... socialist and Communist governments. Just ask the Ukrainian, Chinese, Ethiopian, and North Korean peoples about that latter!
As for racism, ask the Chechens and other Asiatic minorities about racism in the USSR. Ask the Tibetans and non-Han Chinese about racism in China.
