Maybe some people dislike you and are downvoting all your comments because if was you who wrote them ("karmassassination"). But all of your comments are low-quality enough for downvotes, taken individually. People are not disproving you because you sound like a troll.

If you're not actually a troll, please lurk more, try to understand the norms around here, read up on the standard answers to everything you think of posting (e.g. look for other posts on cryonics here and Alcor's FAQ before you say cryo sucks), and find the most on-topic posts to comment on (old posts on whether cryonics is a good idea, rather than a new post on how to sign up for it). If you want help with that, answer here or message me, we'll start Accidental Trolls Anonymous. If you want to argue that your posts are not actually obnoxious (as opposed to being involuntarily obnoxious because you don't get LW yet), I'll just ignore you.

If you posted something not obnoxious, I'm inclined to believe the community would, in fact, upvote it.
