How do I help my daughter when she is stuck in an idea or thought?

My daughter has it stuck in her head that she absolutely doesn't like boys. Of course when I ask her why she says, “because they don't have long beautiful hair like girls”. So I say, "wow that's interesting, I choose if I connect with someone based on how kind they are not what they look like" but it falls on deaf ears. Last week we went to a friend's house and they have an 8 year old son. She spent the first 20 minutes there screaming "I hate boys, I never want to play with boys, this is so stupid." It was really embarrassing. Once she finally calmed down she played with him and had a blast. Then this week we met a friend at the pool who has a 4 year old son and she did the exact same thing but this time refused to have anything to do with him and kept yelling at me that I was talking to the Mom and not playing with her (I was doing both). How do I handle this?
