Authority is never legitimate. Those that claim special rights to it because they bring "truth" or "reason" are the most suspect of them all.

> Many authortarian regimes will "purge" as many of the country's intellectuals as they are able.

This is a letter not the killing fields.

> It matters because it influences what people think

That people find this a defensible position and believe that just finding the "right editors" or "true guardians" can vouchsafe this poor outcome for humanity is always surprising to me.

Shouldn't people have access to reported information and then come to their own educated conclusions?

> If there are no examples of successful labor movements, then why would you hopelessly start one?

The existence of Wikipedia is a convenience and perhaps not one that should be given tax free status. I think the selected history of labor movements will be just fine.

Even if Wikipedia died tomorrow because of one letter you could still walk into any bookstore in America and buy a book on any subject you want.

Because it's a convenience?
