I think it's funny until it's your daughter their talking about.
Unfortunately, in this world, ignorant bigots (r.e. Imus) exist and we sometimes are reminded of their idiocy.
Thankfully for your daughter, she has a Dad that will teach, support, and help her build her self confidence so that words don't leave a lasting effect.
I know you take your son fishing, but you better be taking her as well!
