ya i read some of those. Unfortunately that can happen, it is the internet. Look at all the horrible and inconsiderate comments posted on youtube videos of the earthquake and tsunami. People use the internet to be dicks with the confidence that no one knows who they really are (which isn't true, it is incredibly easy to find out who someone really is), and they use that as an excuse. its quite sad.
There were some good comments to which is great :)
