This is a very good piece of work. I like the message you are trying to spread, and the gentle compassioned voice you are spreading that message in.
That's all not to mention the fact that I have the same general attitude towards bad reviews, you know, you just have to take them in stride. Don't give up. As well, I feel there are better writers on this site than I could ever be.
Great appeal with a great message, given with a gentle encouraging feel.
