It's more egalitarian and accessible than any other social media I can think of, yes.

In 4chan a literal nazi, a drag queen, a bona-fide pedophile and a luddite can exchange opinions with no prejudice, because none of them know anyone else's background.

You might think that these people can't talk about certain things, but any subject in which discussion becomes too caustic simply doesn't even take place in other platforms, and not every discussion is a life or death discussion, they can talk about photography just fine.
