It's completely natural to like some opinions and not others. What people find off-putting is your false objectivity, not your stance itself. Even many people who disagree vehemently with my opinions would not classify them as "ideological boilerplate" or trolling.
Not to speak for grandparent, but he seems to be commenting on the systemic pro-startup bias (for which you are not necessarily at fault) of this site. It does get repetitive, because the presentation is so one-sided. A lot of encouragement is given to a strictly positive view of venture-funded startups: that they're the future, that they're the best way to work, that anyone who isn't in one is missing out, and that while there's some ugliness it's better to rely on evolutionary improvement than revolutionary overthrow, as if you can analytically solve The Problem, sit down and talk to it and tell it that it's been solved, and it will go away.
What's also left out, systematically if not intentionally, is discussion of what happens to people who don't eventually win the startup lottery. Failure is presented here as a temporary setback on the way to inevitable success, which ignores the fact that for some kinds of failure are worse than others and sometimes people aren't as forgiving as they should be.
Finally, there's very little attention given on Hacker News to the extreme disparity of equity between founders and employees, and the fact that the reasons for those discrepancies are almost entirely sociological. Encouraging people who have the social resources to become founders, to do so, is one thing. Encouraging 22-year-olds to become startup employees without advising them on how to become something else 10 years down the road (when they don't win the startup lottery and need to find stable, adult job positions that come with respect, remuneration and authority) is, if not irresponsible, at least negligent of the bias it upholds.
