What do you think of judgemental people on Y!A?

Let's face it, we've all judged people on here, leaving them answers that are sometimes rude, or just simply stating the truth, despite the fact that it will hurt the asker. What I don't understand are the people who wish you ill just because they don't like your response. Are people not allowed to say what they think on Y!A, within moderation of course? I mean, if you post a question on Y!A, you are willing to accept the fact that there are answers you will obviously agree and disagree with, but that doesn't mean you should wish ill thoughts on the ones you don't agree with. Example: Yesterday, I answered a question written by a high schooler asking if anyone was a teenage parent and if they were in love with the father. I replied that I was never a teenage parent, and that I was too smart to become that. I should have elaborated because I got slammed by a teenage mother saying I was judgemental and that she wished ill on me.
