Can I keep my daughter away from meeting her favorite author?
Why would you keep your daughter from meeting her favorite author?
I just don't want my daughter to look up to him anymore.
It is incredibly rude to deprive your daughter of meeting her favorite author. It would be a big deal to your daughter and you should support her wishes.
Don't tell me what to do. If she needs something to look up to maybe I'll get her a teacher or famous artists.
You asked for my opinion and I'm just letting you know that I personally think that people will think you're being far too controlling in keeping your daughter away from her favorite author. Your daughter will probably also grow to resent you, too.
