Please don't resort to sinister explanations without evidence, when a topic is plainly divisive. It's an extremely tempting but low-quality discussion move that the site guidelines explicitly ask everyone here to refrain from:
If there's specific reason to believe that comments here are somehow being manipulated, that's different and you should email hn@ycombinator.com so we can look into it. (That's in the site guidelines as well.) But the overwhelming majority of the time, there's zero suggestion of any such thing, other than people disagreeing, which is evidence of nothing but that the topic is divisive.
