In practice every representative system has ended up being dominated by an elite of one kind or another. If it's not corporations then it's some other elite.

Socialism cannot coexist with government. The state is an organisation with a monopoly on legitimate violence. If you have a classless society and a government then the buerecrats that make up the state will use their monopoly of force to establish themselves as a new ruling class. That's what happened in Russia.

"An anarchist who supports male domination contradicts the implicit critique of power which is the fundamental principle upon which all of anarchism is built. Sexist anarchists do exist, but only by virtue of directly contradicting their own anarchism. This contradiction leaves sexist anarchists open to criticism on their own terms. Anarchism must be feminist if it is to remain consistent" - L. Susan Brown
