Dude, this is exactly what you are doing. You have wandered into the fediverse that welcomes everybody and you are upset that not everybody agrees with you on everything and that justifies you being a dick. You are exactly the thing you are hating on in your head canon self righteous hero narrative.
Take this moment to reflect on your first instinctual mental response. Is it "but that's because I'm right"? Think about this and what it implies.
There are terrible people everywhere and in particular everywhere online.
This is why I would never be bothered moderating and I am reluctant to release anything to the public of what I do for my own enjoyment. Cheers to moderators and people that post their art and comics and other stuff online.
