Julie went through a pre-concept situation, where the leaders of an association she wanted to participate in used her appearance as a way of assessing the skills and abilities she had.
As we already know, people should not be judged on the basis of their appearance, but on the basis of their actions. This situation of prejudice, made Julie upset and sad and caused her, a feeling of revolt that made her join with a friend and make a peaceful protest against the association.
The first constitutional amendment states that every American codadão has the full right to protest peacefully against any situation of injustice and against any institution. For that reason, we can say that Julie can make her protest and that IQ Rules the World cannot stop her.
