Earlier quoted context omitted.
It's a mistake to think that deep pocket YC investors will suddenly become aware of current events that otherwise escaped their notice if only current event stories made it to "the front page of HN". Another mistake would be to think that [flagged] and down weighted submissions do not get many many eyeballs and that C-suits of large SV and other tech companies don't take part.
Every reminder that powerful people see that the status quo is unacceptable has value. It's also obvious that a post being flagged reduces the number of people who will see that post, that's the whole purpose of flagging.
If it's really true that "some of the richest and most powerful people in this country and on this planet look at this website", what do we want them to see here? Do we want them to see enraged people saying the same things that they keep hearing over and over and thus dismiss as background noise? Or do we want them to see intelligent, thoughtful people having sophisticated discussions and making new points that might give them pause and provoke them to think about things in a different way?
