You don't "irrationally" hate them probably because you happen not to fit the target profile.
EDIT: And are you serious? You truly think that KiwiFarms is a quirky, harmless place that just collects info to do nothing with it, and at the same time believe that on HN you'd be targeted by people who'd try to ruin your life? What force keeps such nasty people off kiwifarms but allows their presence here, I wonder?
> Yes, Kiwi Farms exists and has information and opinions you might not like. It certainly has ones that I don't like. But at the end of the day, it's just words on the internet;
There's no such thing as "just words on the internet". Words express beliefs and intent. I take them seriously.
> the stuff about "organized harassment campaigns" and all that is a media lie.
Of course. The sort of people that compile elaborate profiles on people including personal information are some sort of enlightened beings that despite obsessively tracking down and compiling every embarrassing or weird thing about another person would never actually use that information for anything at all.
