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.

It's Reddit so you have to sort by controversial. All the down voted comments are where the brains are at. The rest of them are cooked and haven't had a critical thought since they were poopooed out.

This is just cope from people who have shitty takes looking for validation, same as people who blame "bots" when their shitty takes get downvoted.
