Interesting stuff.   So you seem to imply that the state of Oregon had a prejudice against Catholic schools in particular?     How does this link to the conservative protestant churches  of today?   Not questioning your history at all, it's fascinating.   As a young Oregonian I had no idea of the reach of the KKK in Oregon at one time.

There are many abominations that have been justified through religious affiliation.   That is NOT meant to be an indictment of all religious people, not by a long shot.    But spiritual folks have got to be careful then don't sympathize with organization like the KKK or modern white supremacist, just because they use a label of  Christian, Muslim, Jewish, etc....      It should be Christians who state with humility, that they will not support bigotry and discrimination.    You can't defend bigotry just because it's confiscated  your symbols of religious faith.

*As a Christian I will not support any teaching of creationism as science.
