A lot of people naively interject "But we're not a democracy, we're a Republic!" at arguments where it has no real bearing, but _here_ it does.

We (America) are not a democracy, we're a constitutionally limited republic. Republic is a subset of democracy, but the 'constitutionally limited republic' part is important. We cannot elect politicians to censor the things that we want censored because our republic has not authorized the government to do censorship, and the bill of rights expressly forbids it. They are constitutionally limited from doing so until and unless the constitution is amended.

Until and unless we change the constitution, any efforts to do that are illicit. Popular democracy would allow a majority to vote to bring back slavery, and if you don't like that, you don't like democracy.
