Racism is a form of dehumanization, and all forms of dehumanization must be combated with solidarity.
If we ever feel alone in our suffering, we need only look to the Cross.
Even though Jesus is God, he allowed himself to suffer so that he could enter into solidarity with us.
It is important to remember that Jesus was fully human as well as fully divine. His humanity is what allows us to unite ourselves to him and, through him, to the Father.
