Subjective relationship with theologies.
Though it would be a wonderful world of knowledge to respect and learn about other belief systems, many parents do not believe in this format.
If parents wish, they could send their child or children to a Catholic or Protestant school verses a Government Public School.
This is very sad, as children, do not have a racist bone in their bodies. They are open and play with all children, white, black, Catholic, Protestant, Hindu, Muslim, Jewish etcetra.
It would make a better world !
Just turn one´s head and take a look at this world .. Most of the wars have been because of a racist nature or a theology ..
