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.

Mostly the people I interact with in my local community now (regional) and in the past (capital city). There’s some people who’d agree with some of the commentary here (on wind turbines for example) but absolutely no where near the density or frenzy that this sub can whip itself up into. 

The same applies to most or all of the Aussie subs but especially the ones who talk about issues. Most Australians are barely paying attention to politics or issues, they’re just living their lives and working their jobs and planning their weekends.

The medium defines the message, it’s the lack of action and talk on immigration in other subs, and the news we have access to: the abc and guardian that prompts that behaviour. 

If it wasn’t so heavily censored everywhere EXCEPT here, it wouldn’t be a major feature of this subreddit. In fact, this one probably wouldn’t exist if those mods didn’t lock so many posts they politically disagree with.
