What ModernMech said. I think what that other often downvoted user said made a lot of sense and that he's wrongfully being downvoted, so I wanted to talk to him in private and share our experiences. There is nothing wrong with that.
Also, "users here are very tolerant of that" — I'm sorry, I have to disagree with that hugely. You say I'm "suspicious" because... I have repeated behavior of being suspicious? That's a circular reasoning.
Also, this "repeated behavior of being suspicious" actually means "repeatedly having a different opinion about China". How is that being tolerant again?
It is exactly because of this that many people don't dare to post alternative opinions about China on Hacker News -- for fear of being socially ostracized. By chance I happened to encounter a few people on Twitter who turn out to be one of those so-called "bots" on HN, and they told me they posted anonymously because they fear the shit that will land on them (downvotes, accusations, more) if they post with their main accounts.
There is nothing suspicious about not answering about a subtopic. I can say things when I want to and not say things when I want to as long as I don't break any rules. I also don't answer about Hunter Biden for example, and I don't have to.
I already said many times before why I have a different opinion and I post so often about it. I am Chinese and I am fed up with the lies, propaganda, villification and manufacturing of war consent. There is nothing suspicious about speaking up when you think there is something wrong in a community.
In fact, I assert that the only reason you think such behavior is suspicious is because you have been too influenced by anti-China propaganda. You and the mainstream media have such a warped view of China in your minds that any message that deviates from the mainstream view automatically looks preposterous or fake. But here I am, a westernized Chinese who posted nearly nothing about China for 20 years of my Internet history, suddenly posting about China after having witnessed on the ground in early 2020 how many lies the media told about China and COVID (and as it turns out, many other topics as well), and being shocked and enraged at that. With a non-westernized Chinese citizen you can still say "oh but he's being censored/forced/brainwashed". As a westernized Chinese I have free access to information on both sides and I understand the western viewpoint very well. As a software developer who has developed stuff that hundreds of thousands of sites around the world uses and who has helped numerous clients, I have demonstrated my ability to do independent research. If there is anybody qualified to have a legitimate opinion about this topic, it would be me. So maybe you should seriously consider the possibility that, no maybe I'm not suspicious, it's you that may be wrong and that I may be right, and that the truth is in fact so far from that what you believe that the truth looks suspicious even when it isn't.
