The fact that you're taking the time to make an account and post comments tells me that you value the ability to influence people's minds. Posting ad hominem attacks on Hacker News is counterproductive to that goal. It will attract downvotes, which will turn your comment white and make it hard to read. Comments that are hard to read don't work very well for influencing people. Also, even if your comment weren't downvoted, ad hominems still tend to inhibit your words' ability to change people's minds. You'll be a more effective writer if you eschew them.
