why is someone acting irrational on a rationality website?
The obvious answer is that people here are humans and not Vulcans. But I don't see the irrationality you are talking about. Rationality doesn't specify values or goals. You know nothing about the person who downvoted you or the reasons he did it. Given this, your accusation of irrationality seems... hasty. Even irrational, one might say :-)
If you want people to ask you stuff reply to this post with a comment to that effect.
More accurately, ask any participating LessWronger anything that is in the category of questions they indicate they would answer.
