All socialism is democratic, so "democratic socialism" in practice either means reformist socialism, social democracy (capitalism with safety nets, usually dependent on imperialism), or is a means to distance this new socialism from the really existing socialism in the world today and historically. Reformism is wrong and doesn't work, social democracy is still capitalism and depends on imperialism in the global north version, and the last is just red scare "left" anti-communism that reeks of chauvanism.
