It's more a strategic reading of the landscape. Direct confrontation plays poorly in HN comments, and attempts to do so will be futile.
There's a subtext to the moderator response in the thread linked above: if you do want to engage in direct political discourse, doing so within an article submitted to HN is far more likely to be successful. The submission queue is a more powerful instrument than the discussion thread. Focus efforts there principally. That doesn't mean "don't play the comments". But recognise the limitations, ground rules, and limitations in doing so.
(Review of my own comment history should show the types of confrontation I'm finding generally useful. I usually aim less at changing minds directly than at exposing hypocrisy and/or motivated reasoning, or similar faults.)
Your submission history suggests you haven't been utilising that approach. You might give it a shot.
The submissions queue also affords the option at encouraging others' efforts in the direction you'd like to see. It's also possible to contact HN mods directly (again: hn@ycombinator.com) and recommend posts for the 2nd chance or invited submissions queues. I've found mods quite receptive to this. My practice is to not recommend my own pieces, though that's apparently permitted.
