I don’t think complaining about flagging in general is helpful here. Science hasn’t ever meant that all viewpoints are equal. That would just be chaos.
It’s also not decided by popular vote, but if you want peer review instead, then you’ll have to read a peer-reviewed journal rather than Hacker News comments.
I wouldn't claim all views are equal either, but people are mighty quick to jump on how misinformation is defined (even when that's been proven wrong) here, I don't equate it to many other things
Lot's of cranks are not sharing any information at all (so can't even be classified as "misinformation"), but pure unfounded opinions without any informative content (e.g. https://news.ycombinator.com/item?id=42583516).
This is one topic where the establishment view is mostly wrong and people broadly engaging in censorship are on the wrong side of history, period
