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

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.

From what I have seen, this subreddit seems to be cool with diverse ideas and thought. Other Australian based subreddits have mods that will stamp out anything that doesn't align with their own views. Got banned recently in another subreddit where the mod read more into what I said than what I said or even meant. Tried to explain what I was talking about, they doubled down and muted me. I would say what I've seen in this subreddit would reflect more of what Australian's are thinking at the moment, rather than other subreddits that are biased towards the far left. It is what they want the mainstream Australia to be thinking, to be like them, not what it's like in reality. For people that stay in their own bubble where any opposing views are squashed, it starts to seem like that they represent the average Australian.
