Really, there are probably two elements to this: 1. Your posts could perhaps be a bit more thought out or inspiring. 2. You have correctly noticed that down-vote etiquette here is quite bad. People frequently down-vote posts that are constructive, but simply on the opposing side of the down-voter's position. This is bad, but I really don't see a way to change this behaviour. As an aside, I'm curious why you want karma, it provides little benefit, the main of which, is the ability to down-vote. I'm am not at all saying this is the case, but it would be awfully ironic for you to want to gain karma to get the down-vote ability, only to add to the poor down-vote etiquette.
