Ask HN: (discussions) should comments stand on their own?

I rarely use the "newest comments" view (https://news.ycombinator.com/newcomments) but now I clicked on it and saw a list of various comments without surrounding context. Yet, there are the buttons to vote on them.

That made me think, do people peruse that list and vote regularly solely on the comment's content without context? Suddenly some irrational voting patterns start to make sense, if there are people voting "blindly".

Should the view have vote buttons at all, make people to see some context before deciding on a downvote?
