I don't know if this has been said befor but of the few pages i've seen in this thread, the premise seems to be that of physical bullying.
It appears that the majority of posts refer to E types bullying I types at school.
While this may be a fairly true generalisation it misses a huge niche in the bullying world.
That of the psychological bully, which i think would actually be more suited to some I types or infact pretty much any type...possibly barring isfp's who seem to just always look after people. (sweeping generalisation sorry isfp's)
I sort of bullied once or twice, and was sort of bullied once or twice (at school)
Relationships after school friendships/work collegues/so's usually contain some level of bullying, some severe.
