All right, I'll bite.
>HN's community is a pit of sexist villainy, unnecessary pedantry, empty sycophancy, and vapid self-aggrandizement.
Then why are you here? I'm not asking you to leave, but that is such a thorough indictment that I do wonder why you stay. There must be more to the site than that.
>PS: I downvoted every single comment in this thread that rubbed me even a little bit the wrong way, regardless of its constructiveness. I left no comment in explanation. I took special delight in doing so for comments with an especially righteous tone. The world is no worse for my having done so. The community would have been no better had I restrained myself.
One person downvoting like this is not much of a problem. If very few people behaved like that the OP would not have needed to post this. If everyone behaved like that the site would be unusable.
>Downvotes are not the problem.
Thoughtless downvoting is _a_ problem. I don't know if it's the biggest problem the site has but why would you let that stop you from addressing it?
