This comes off to me as a more refined "Yes of course, what did you expect you naive person ?" type of comment you often find online (somewhat common among radical leftists)
Maybe commenter agrees with you that the point is to empower a national police to subjugate the populace (This opinion does not raise any of my eyebrows) but do you think this is going to reach people who don't already think that ? To put any doubt in their minds ? I understand the anger the current situation is causing and I am guilty of breaking the hn guidelines a few times myself but I am also convinced of the need to actually explain what you think are the actual problems from the ground up rather than just casting your own conclusions onto people, no matter how obvious they seem to you
So I did think they did a good job with their comment
“You know those problems you’re pointing out? Well if you listen to the people in charge they are saying they aren’t problems" is much better than "Duh, what did you expect ?"
No matter how obvious you think the context that led to your conclusion is, it's always worth it to share it along, especially in times of information bubbles
