Where would we be without these stories?
Where would we be if the gender issue had been raised thirty years ago?
We don't know what the future holds so we stumble blindly into it, each one of us secretly thinking we know what's best for everyone, what the 'right' thing to do is.
The trouble is, we don't know what the right thing is, because the right thing for me, is probably the wrong thing for you (or any other person) and that's when we start to judge others, start to tell people how to live their lives.
If you don't want to read fairy stories, if you don't want your children to read them, that's fine, that's your choice but don't you dare take that choice away from other people.
