Mini Academy CDC, Denver NC review: Disciplining of Children

My son was 16 months old when he started here and one of the "favorites" was almost 4 but was apparently mentally handicapped. They continued to allow that child to stay in the 1-1.5 year old class. This child continuously bit my child over and over everyday...my son finally bit him back in the same manner (over and over) and was kicked out of the daycare.

What ever happened to equality of the people?
Mentally handicapped or not. It doesn't give them the right to decide which child is better than the other!
