Let me explain, first you express your opinion as a matter of fact. Their opinion is nonsense? Why not pose a question as to why one may think that? Consider the culture of 4chans various boards and some of the herd mentality you see on hn.
I can tangibly see on a daily basis trite comments which add nothing of value be upvoted because it expresses commonly held approved opinions (ie. Anti amazon comments or issues with nimbys in sf)
However someone echo a concern about the importance of us military intelligence infrastructure by virtue of supporting msft contracts with the us military, someone is downvoted as a warmonger with little discussion.
The shitposts are real randy
