While I have never purchased a book on feminism, it is clear that the capitalist system funds women to write about it.
In contrast, in modern socialism, we do not write about feminism ourselves because we believe women and men are truly equal.
This belief shapes our broader aims as modern socialists: we strive for true equality among all people, regardless of color, ethnicity, sex, religion, or other differences.
In contrast, the capitalist system opposes class struggle, but we uphold it, aiming for the proletarian world to gain power.
