First off, opening a comment with "Hello Troll" has to be the most childish and reddit-like way of opening an HN comment I have ever seen. If you think GP is a troll, you can simply not reply, indeed you are practically obligated by the guidelines not to. Once you reply, you are obligated to at least pretend you take the claims that you reply to seriously.
Secondly, why are you responding to "Those topics are censored" claim with "Here are all the correct answers to those topics that my media tells me to believe"? GP didn't say whether they think there is a correct answer to a topic and what, if any, may that answer be, GP has simply observed that those topics are heavily and nakedly suppressed in legacy media and social media, often with hilarious results (e.g. Instagram banning Cochrane, a medical database of the highest quality, simply for mentioning Ivermectin).
Contradicting GP here would consist of bringing up evidence that those topics were, on the contrary to GP's claim, discussed fairly and found wanting. Talking about correct answers are irrelevant, we're talking about whether all questions and answers are allowed for discussion. Because Americans are often shocked that China hates things they consider elementary and bans them, GP is simply saying their own society frequently and obviously engages in this as well, often with cheering from those self same people.
Third, some of your points about masks are self-contradicting. If the CDC lied about masks once, why wouldn't they lie twice or third or tenth? You would be a fool if you trust a liar after the 1st time, and medical institutions have proven to be thoroughly partisan and rotten and corrupt during the entire crisis, anybody taking a covid-related claim from a medical institution at face value is a prime target for bridge selling.
Another point is that masks come in types, and only very few types protect adequately against the latest covid variants, and the vast majority of people don't buy those types (N95 or KN95) or don't wear them correctly. So masks, as worn in practice, are indeed very close to useless, as evidenced from the fact that they're not predictive of viral spread (i.e the fact that a country's population wears masks has no better than random chance correlation with whether it has lower infections, i.e masks are statistically useless).
This why your correct answers are wrong, at least in part, some of the time. This is why you need to be constantly questioning them, and not rushing to defend the censorship loving institutions and corporations who have no particular interest in you or your well being, and all the interest in Power and Money and Status.
Fourth, why the hell are you bringing up more evidence for censorship as evidence against GP? You're supporting them, not contradicting them. GP never claimed the censorship is done by only 1 party, only that is done. You're arguing for GP's claim while thinking you're arguing against.
