This experiment was real in the earlier era of the Internet. And the answer is: When censorship isn't universal, and there are lots of more or less free spaces to speak in, extreme views don't get concentrated and exist everywhere but at a much lower level of intensity. The mainstreamers are less ignorant too because they actually have some exposure to arguments and counterarguments against these views as opposed to just vilifying and banning the others.

Lots of other benefits to this model - names that people don't get trapped in extremist bubbles as much when they're not literally banned from everywhere else.

What? Without censorship a single line of thought, the most vocal, comes to dominate while a majority of people who disagree decide to leave for a new place. This happened all the time in the early internet, it happened to 4chan after Obama became president and it happens in subreddits everyday.
