And you can always come back as bigiain2 or ratsmack2 later...
Assuming that HN/YCombinator “owes” you any points reputation is a pretty silly point of view.
I guess there probably are some cases where YC (or other) backed startups might judge people based on HN meaningless internet points, but if you care about that, perhaps your choices to argue vehemently enough against the groupthink here are nit great choices for you? You probably aren’t waging a vegan or anti surveillance capitalism war of words on your LinkedIn in that case, you might want to keep personal crusades out of your professional persona here if you are playing a profession persona here?
Or own the personal crusades, because if Facebook or Google refuse to hire me based on my privacy stance in my HN post history, or Palantir refuse to hire me based on my distrust of law enforcement? I’m totally OK with that. I will back out of arguments with Googlers or Facebookers well before things get to punitive downvoting stage though, just for my own sanity...
