Those sound funny; why would they make you sad?
There are many compounding factors but I experienced the live internet and what we have today is dead.
So I go on my province's subreddit. Politicswise, if there was an election today the incumbent politician would increase their majority and may even be looking at true majority. Hugely popular.
If you find a political thread, there will be 500 comments all agreeing with each other that the incumbent is evil, 50 comments downvoted and censored because they dare have an opinion that agrees with the incumbent, 100 comments deleted by anonymous mods banning people for what reason? Enjoy your echo chamber.
Anyone who experiences being censored a few times will just stop posting. Then when the election happens they have no idea at all why people would ever vote that way because they have never seen anyone do anything but agree with their opinion.
What an utterly dead subreddit.
