Disturbed yes.
Offended no.
The children ones disturbed me -- ooo let's dress up little Johnny like a pimp. Who are these people?
Wanders off to bed looking incredulous and sleepy.
I'm with you on the children's costumes.
What I find far more disturbing, however, is how some people dress their kids (especially little girls) when it is NOT Halloween. Much too sexy and grownup--the little Diva costume is not too far off the mark, sadly.
