This makes me think that you might not have taken in the essential bit, which is the pattern of an account's behavior. Was that not clear from the above?

In case it helps, the issue is that we don't want accounts to use HN primarily for arguing about politics or ideology. That's an important test and has proven to be one of the more reliable ones, in terms of whether an account is using HN as intended or not (https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...)

Separately from that, looking at https://news.ycombinator.com/posts?id=123yawaworht456, I see other reasons to ban such an account—you've routinely been breaking HN's rules in plenty of ways which have nothing to do with your specific opinions. If your motivation is simply to protect yourself, as you say here, then I wonder why that would be.
