Perhaps, I'm not that familiar with the "spirit" of HN, but that comment seemed pretty mild to me.
To your last sentence, first, yes I believe what I've written. I am an Australian citizen. I personally don't think I do enough to "right [our] wrongs", but that doesn't stop me believing in the principle of democratic responsibility. I recently have gone to a Climate Change protest, voted, and donated 10% of my salary to helping people who deserve help but aren't getting it from our government. Day-to-day I also avoid participating in activities I believe are wrong but which are made illegal/regulated in my society (eg. eating meat).
But again, the above is kinda besides the point. I believe in democratic responsibility so look first to question what I'm able to do rather than blaming some third-party, and wouldn't complain about "you guys chose..." phrasing.
