The book gets quoted quite enough. But quotes are really bad arguments.

Here’s one that flies in the face of the Orwell’s:

Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them. [...] We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant.

- Karl R. Popper

In practice we’ve seen both ways play out badly. So clearly we can’t just hope that full freedom is good, and good guys will win.
