In the US it seems that the first amendment's principle is very, very clear in that regard. This was the draft proposed to Congress here below, which is longer than the final version but clearly represents the thinking behind it without ambiguity:

> The civil rights of none shall be abridged on account of religious belief or worship, nor shall any national religion be established, nor shall the full and equal rights of conscience be in any manner, or on any pretext, infringed. The people shall not be deprived or abridged of their right to speak, to write, or to publish their sentiments; and the freedom of the press, as one of the great bulwarks of liberty, shall be inviolable.

In other words, the first amendment is clearly against censorship of any kind.
