Actual discussion on what?
You've said you don’t like people being unhappy with the system they're forced to live under, and that it annoys you that we talk about it? We have solutions, we have two centuries of theory and historical examples, its not our job to teach you all of this if you're not willing to learn it yourself. Its not hard to find this information online, why should we always engage in intense debate? It was exhausting on reddit and 99% of the time it ends in bad faith arguments and you've wasted an hour of your time on someone who was nothing worth more than a ‘k’ and moving on.
If you so desperately want to see other content, foster it yourself. You could start your own community or instance and put in the hard work to see what you want to on the Fediverse. Its no one else's job to cater to you, you have the tools use them.
Frankly I fucking love this place, it’s the closest to what the Internet felt like 30 years ago and my interactions with most people have been bloody enjoyable.
