But yes, the effect is pretty much that.
What could make me love the established media more than a narrative that 'uncensored truth' would turn me into some kind of QAnon zombie.
I simply cannot handle it.
As for the others on your list, non-alt-right people (cf. non-alt-right sites) might be more inclined to discuss (cf. host discussions about) these "facts" if their primary use wasn't to be woven into otherwise fictional narratives claiming to be coherent justifications of racism and homophobia.
So, the same thing mainstream society has been doing for the last 6 years, just for different races and groups?
If they criticized things like Outreachy (which literally discriminates people based on race and gender [1]) with the same energy that they criticize the "alt-right" then I would believe them. Otherwise it's just hypocrisy.
The challenge is that when they come into conflict, we know that humans tend to discard the facts before the world views.
There are also plenty of things that can't be discussed in alt-right places, only in proper free-speech places (which are rare and often heavily contaminated with alt-right due to them being kicked out of everywhere else). E.g. if you wanted to discuss whether "consensual child molestation" is actually harmful you'd get banned from any right-wing space.
Hate and stupidity breed more hate and stupidity. If we approach this situation from a generic perspective we can defend free speech and argue against censorship; but if we talk about speech such as antisemitism, homophobia or black people hate, we cannot defend it anymore.
While there is literally not an “Alt-Left” there are 100% Far-Left ideologies that a a hypothetical “Alt-Left” movement would most likely match to. The Left is the entire spectrum of the left, which is many things. [2]
Liberalism as a whole is not Centrism, . Social liberalism fits in Centrism which is a subset of liberalism.
Mind you also the Left-Right political spectrum does not equal the American Left and Right. It is a long history of observation including Alain’s reflections on the French Revolution and the study of international relations today. Hypothetically, the American Left could very well be on the Right and the Australian Left could be on the Left.

Does this mean that only the alt-right have access to uncensored information?
