Getting the actual conversation and actual article you tried to post gives a lot of context into why you believe you were cancelled. I don't want you to out the mods, I want to understand their side of the story.
I've heard your side, and it sounds like the content didn't fit the vibe of the subreddit, as per the mods. They told you that and you threatened to break their rules again. Yes, you were threatening to break their rules.
I'd say they gave you a chance, and given this particular story re: mod harassment, didn't want to engage with an aggressive user.
> No rules broken, just intimidation and censorship.
A moderator of a forum asking you to not do something is not intimidation. It's asking you to adhere to the vibe of the subreddit. The description of the article you tried to post was obviously an attempt at rabble rousing on your part. There are helpful and constructive ways to voice your opinion. If you have consistent trouble doing that, I would consider therapy to try and understand why people see you as aggressive when you try to share your opinion.
There's nothing wrong with asking for help when you're struggling to fit in socially, especially if your opinions diverge from the norm. Being different is HARD.
