I can understand that feeling, but it's also unfair to treat hijabis like they have to be absolutely perfect. They are humans struggling, just like the rest of us. Sometimes they do things right, sometimes they don't. I do understand that for some it seems disrespectful to the idea of modest dress that hijab entails.
I know people who objected to hijabis dancing even when it was all girls. They complained why the gathering had been made all girls just so these hijabis can dance? But why not? They want to have fun and celebrate, just like everyone else.
Good, balanced answer
