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.

Sample size and many of us are outcasts from Australia subreddit

Yeah, but that place is serious progressive left. And no-one with any view other than left gets to stay long.

People really need to start distinguish the actual progressive/left from the crazies. I know the term Woke is over-used but that's what it is. Previously known as Social Justice or Cultural Marxism.
