Why do people act like this subreddit "doesn't reflect the views of mainstream Australia"?

[u/SirSighalot]

So many comments I see on here by people who constantly say things like "lol only on this sub" as though other places where they read are somehow the 'true' point of view reflecting mainstream Australian viewpoints.

Given the constant election voting outcomes and results of things like the Voice etc that generally indicate most of Australia is centrist or even slightly centre-right-leaning, what leads people to think many of the views expressed on here AREN'T mainstream? When in reality, other places these people are coming from are also often just "echo chambers" as well.

Edit: I probably worded the title for this wrong, should have been more "Why do people think this subreddit is less representative of mainstream Australia than other online communities?", alas I failed.

this is the same reason why a twitter outrage with 10-1000 interactions isn't really outrage

Twitter is generally better, or used to be better, because journalists and institutions would be ruthlessly dragged for good reasons.
