You might need to go back and read that one again, this is the faintest criticism of a lengthy screed in which the person you are replying to labels user-hostile behaviours as "acting like a jerk" and generally disapproves.

Your counter argument to this is to just be contrarian and imply they are a jerk... because, well, you don't agree with them. You didn't add substance to the discussion (facts, evidence, argument seeking middle ground), you just sought to set fire to someone because you were uncomfortable with the dim prospect you might be wrong/guilty of acting like this/be the subject of the criticism.

Do you see how this undermines your point of view/actually re-enforces the validity of the criticism?

The only thing I get from your reply is that I'm sorry HN doesn't allow blocking users.
