As far as abuse from peers - kids who want to abuse other kids find something to pick on others about regardless of the situation - I've seen kids picked on for:

both following and not following fashion trends;
being a single child,
for NOT being a single child,
for being the youngest in the family,
for being the oldest in the family,
for being the single girl in a family of boys,
for being the child of a single mom,
for being the child of parents who have NEVER been divorced or seperated
for having moved too many times
for having NEVER moved
colour of hair
colour of eyes
colour of their PET!
having a pet
not having a pet

face it - many kids are cruel, vicious beasts. I think they get it from their parents.
