I notice a lot of people responded to you substantively, but you only responded to the ones who didn’t. If you want to advance the conversation, you might respond to them instead of asking the same question over and over.

Yes, if someone writes something to which I have no substantive response (i.e. if any reply I could make would be entirely trivial), and if their point is generally a good point, I simply upvote it and move on. The issue has been aired, adequate coverage has been given to various views; there is no need for the thread to continue indefinetely. It is only when I have a good counter-argument (which nobody else has already delivered) that I reply. (Or, sometimes, when a question is obviously directed at me personally.)
