hmm, i feel personally hor..
that whether a teacher can deal with different type of students, is
another issue which shouldn't be mixed with the issue about
teachers getting these type of degrading treatment from wannabe
preteen punks.
and i think anyone who supports such treatment of teachers, whether
its a "common" trend, so suck it up, or that the teachers "deserve
it", are barbaric animals with no sense of conscience, shame and
morality, and their parents should just roll over and die of
shame.
after spending a good 16 years (at least?) raising up their kids,
they turn out to be such cretins. so can they be considered as an
example of success or a failure in raising up a child? 
oh, for the record, i do not condone teachers who hurl vulgarities
at students too, or tearing up their composition and making them
eat every scrap of paper either. so don't complain that i'm
bias.
fucking cretin.
