There's plenty of evils available to the US Government today. As some people like to point out, a government is an entity that has monopolized violence, which is an arrangement that's largely to the benefit of society (at least, in the cases where it is used correctly).
Execution, jailings, regulations, etc. etc. Plenty of ways for the government to be abused. Its inevitable that we give the government power to do what is necessary in society, whatever it is. Censorship is just one more power that the US Government has toyed with from time to time over the centuries.
To prevent abuse, we need to elect the right people to be our leaders, and the ones who wield that power.
