Libertarian political correctness?
I don't know where you got the idea RMS is a libertarian. Even a quick read of TFA should have clarified that point for you. But quoting another interview:
....I'm a Liberal, not a Libertarian.
I think it is good to regulate businesses in any way necessary to protect the general public well-being and democracy. For instance, I support consumer protection laws, which are needed precisely to stop business from imposing on their customers whatever conditions they can get away with in the market. I support rights for workers which companies cannot make their employees sign away. I support the laws that limit the conditions landlords can put in a lease. I support the laws that help employees to unionize and strike.
All in all, I think it is a mistake to defend people's rights with one hand tied behind our backs, using nothing except the individual option to say no to a deal. We should use democracy to organize and together impose limits on what the rich can do to the rest of us. That's what democracy was invented for!
And we should abolish the "free trade" treaties that obstruct the use
of democracy for this purpose.
But then, as others have already stated, you're on the wrong track with PC to begin with.
