But I am not sure of the outcome - I would like others to defend me when I am accused or picked on for no good reason. Right, and by providing a explanation than just posing the question, you're doing a better job of doing exactly that—showing why you think it shouldn't have been downvoted—while also contributing to the conversation. In my experience, the people who are responding to such questions are not the people who have downvoted—they're doing some version of what I've outlined above. If you have no idea why something might be downvoted, it likely would be good for you to stretch a bit and imagine how someone else might read or take the comment you're referring to. It'll likely make you a better comment writer and reader.
