By any chance are you trying to troll? I just told you that you were being downvoted for blogspamming, insulting people, and unnecessary personalization. Your focus on Vladimir manages to also hit two out of three of these and comes across as combative and irrational. Even if this weren't LW where people are more annoyed by irrational argumentation styles, people would be annoyed by a non-regular going out of their way to personally attack a regular. This would be true in any internet forum and all the more so when those attacks are completely one-sided.

And having now read what you just linked to, I have to say that it fits well with another point I said in my earlier remark to you: you are being downvoted in a large part for not explaining yourself well at all. If I may make a suggestion: Maybe try reading your comments outloud to yourself before you post them? I've found that helps me a lot in detecting whether I am explaining something well. This may not work for you, but it may be worth trying.
