You got banned because no one wanted to be around you, there is no nice way to say it. Not just having awful takes, but repeatedly going on rants even after people told you to stop. Whenever someone told you to stop going off-topic and starting what are essentially flame wars, you then started screeching about being silenced. You also bash random people at times about their contributions not being good enough to you, which is uncalled for and toxic. Your article reads like you view yourself as the victim. But you are not one. I am surprised you even made an account just to whine at me on lemmy, which is a leftist social media platform, I'm from one of the anarchist instances even.
If someone made it clear to you that you made everyone uncomfortable, then maybe you would get it (I am guessing you have trouble reading social cues) but instead they "troll hugged" you until they got sick of it. The "code of conduct violations" (aka bigotry) is why they got rid of you. You can write the best code, but it does not mean people will be willing to work with you. You will not be able to find some magical rule to win and get unbanned like a lawyer in a legal case. It is not stalking either when people don't want to be associated with your views, let alone their project they have been working on for years. Your views are harmful to people in real life. But you dismiss the very real harm and hand wave it as a "culture war". That is incredibly messed up.
It doesn't matter what anyone says to you, you disregard whatever people say because you just have to be right on whatever subject comes up and you feel personally attacked like the injustice is happening to you. That is exhausting to be around. You should aim to be more empathetic. Picture why the other people were uncomfortable, why they asked you to stop ranting, why they banned you when they are supposed to hug trolls until they feel safe enough to open up and change (supposedly, I maintain that doesn't work with randos). My solution is to get a therapist, I know that sounds like I'm being mean, but a therapist can literally break this down for you and help you uncover why this happened, all in a safe place. You need to reflect on this. Or you are doomed to keep repeating the same mistakes.
