If we don't believe in freedom of expression for people we despise, we don't believe in it at all.
I think it only makes sense to seek out and identify structures of authority, hierarchy, and domination in every aspect of life, and to challenge them; unless a justification for them can be given, they are illegitimate, and should be dismantled, to increase the scope of human freedom.
It’s ridiculous to talk about freedom in a society dominated by huge corporations. What kind of freedom is there inside a corporation? They’re totalitarian institutions - you take orders from above and maybe give them to people below you. There’s about as much freedom as under Stalinism.
