I find that, as trite as it sounds, you really do get out of HN what you put in. When I first posted at HN I adopted an aggressive, frankly really fucking douchey attitude that reminds me of your continual one. I'm still slowbanned because of it[1]. When I moderated the dipshit attitude out of my posting, however, it became a lot more fun and I've made a few friends through posting here.
Let's get real here. Ideological downvotes aren't your--and I mean your, in particular--problem. Being an asshole, who apparently can't get through a day of posting without attacking someone or caricaturing a position with which you disagree, is. I mean, come on. "Fandroids hate Apple." "Leftists hate private property." You're not fooling anyone: the schtick you are employing is to make statements that are tailored to offend, under the guise of "stating your opinion," and then get outraged when they do offend and people take advantage of the moderation mechanism of a downvote to say, "we don't want this here." You don't get to be surprised or offended when you do that and conflating rejection of your behavior with rejection of your beliefs is intellectually dishonest.
The problem with the reception of your posts is you. I know this, because I've been there, and I chose not to be quite as much of an ass. You, apparently, have not. Act like less of an asshole and I'll bet you that what you see as "ideological downvotes" go away.

[1] - The slowban used to annoy me, but I find it moderates my initial, fly-off-the-handle reaction pretty well. I think I'd miss it if it went away.
