Well when you get upset, I have found through my experience that it is best to back up and remember it is the internet. Trolls can be retarded, but they are just trolls. Stand strong in your resolve. Before posting, have a good understanding of what you are posting about. If anyone gives you flack, flood them with information supporting your statement. It doesn't matter what forum you choose, it is about how you react to those that you interact with on that forum. And don't be afraid to stand up for yourself. What do you have to lose?
