Be warned. The erroneous belief that "free speech" is a right wing concept is exactly the lie right wing lunatics want you to believe. it suits them very nicely.
right wing loonies have a long history of hijacking and destroying empathetic terms like this.
if they believed in freedom or free speech, why is it always them who are burning and banning books? why are they always the ones trying to control other people's bodies? when they talk about freedom, they mean their freedom to take yours away.
should we let them kill yet another canary of a healthy society? that's a different discussion. but it would be a substantial error to assume anyone who won't let them hijack it are actually right wing.
They're right wing in the sense that they're liberals, and I don't know if free speech absolutism is the way to go. But in terms of their pro-freedom-of-information lobbying and legal work I think their intentions are in the right place, even though they lack a theoretical framework in which to contexualize all of the IP issues they fight against.
