I need some sort of AI filter for HN that will not only hide blog posts from a particular domain, but hide other people's blog posts "responding" to those blog posts and then submitted as separate articles.
You should, then give it to me so I can sort out the comments that don't add to the discussion, but keep the replies telling people they aren't adding to the discussion.
No. A strawman is when you give your opponent an argument other than the one s/he is making and refute that instead of the real argument. In other words, you created a strawman and knocked him down, claiming victory while the real man remained standing.
