I agree that we shouldn't teach children equality. Here's my reasons from not so much a parenting point of view but as an educator. Equality usually ends up teaching "white" based culteral curriculum. The vast majority of students are caucasian middle class so you pretend everyone is caucasian middle class and thats how you teach them. Studies of child development and education have proven this just doesn't work. The melting pot theory doesn't work in pratice because there is no equality and your neglacting a large part of your classroom and destorying the childs respect of their home culture.
So as an educator and even as a parent you need to teach diversity vs. equality. Diversity says yes everyone is different and thats okay..in fact thats great..and we need to respect those differences in others and in ourselves.
