Shaq,
If people are sending you messages that are insulting or inflammatory just report it. If it is happening in the forums you are to an extent opening yourself up to it by opening up your training and team management to the community although it is a little surprising that it has been THAT negative.
The important thing, however, is you have the support of people who know what they are talking about and have proven it in the USA community and on the USA team (myself, FC, Harper and to a lesser extent BFiddy...

). Keep doing your thing man and let the haters waste all their energy.
