Other than the first sentence, which is more of a comment, the rest seems fine. Those up votes and points don't necessarily mean what you think they mean ... It does happen that the most upvoted and selected answer be out and out wrong, it is a consensus system after all. Of course the opposite also occurs, and way more often. Like wise you can get drive by down voting, it may very well have been caused by some other question in which you upset someone so they wanted to "make you pay". There are certain people can always be trusted to do certain things, like downvote you on another question when you disagree with them. On individual events it's hard to tell but there are patterns.
The key is to realize that it's a ying and yang thing and don't focus on the points so much.
