I think I'm just going to bail out

Consistent downvotes can be considered a signal sent by the voter consensus that they would prefer that you either bail or change your behavior. Unfortunately the behavior change in question here amounts to adopting a lower status role (ie. more willing to read and understand the words of others, less inclined to insult and dismiss others out of hand, more likely to change your mind about things when things are explained to you). I don't expect or presume that others will willingly adopt a lower status role - even when to do so will increase their status in the medium term. I must accept that they will do what they wish to do and continue to downvote and oppose the behaviors that I would see discouraged.

because on that same post about the Rubik's cube I could of gotten a lot of 'thanks man' replies on e.g. a programming contest forum, or the like, if there was a Rubik's cube talk like this. edit: or wait, it was at -1, then at +2, then at -1

It is quite possible - in fact my model puts it as highly likely - that your current style of social interaction would result in far greater social at other locations. Lesswrong communication norms are rather unique in certain regards.
