so why does he hate robert bruce then?
TheWho hates all children, especially ones that were abused and speak out about their abusers, like RobertBruce did. TheWho went as far as to contact HLA staff menbers (Johnny Ringo and HLA Truth), illegally obtain RB's personal info (including his name and length of stay at HLA), and then "expose" him on the internet as a "disgruntled liar" kid.
This is what TheWho does, people - He insures children that were abused and speak out about it will be punished.
