Why are people so harsh on yahoo answers?

don't get me wrong- most of you are lovely and help me out whenever I have a problem. but some people can be so mean! like when my mum got lost in the Japan earthquake, Im so depressed, I can't do anything, all I can do is wallow away in yahoo. Am I depresses? So yeah basically that was the question and I got a loud of abuse, calling me a Japanese wanker and they hope that she washes up dead on the shore of Hawaii. Should I report abuse? But there's too many to report and ands it made me feel even more depressed.
