I think you are racist if born white and raised in the US. It's unavoidable.
The question is, If you understand your racism, and what you are doing to control your racism.
"I am color blind," is only denial. It is not control.
As a white to say you don't discriminate is to lack any understanding of your white privileged society and your place in it.
Integral to Christianity is the drive to convert others. It establishes an us vs. them mentality. It establishes, by it's very nature and organization, a hierarchy of saved vs. damned and places christians in the superior saved category.
Christianity is the embodiment of discrimination. Discrimination must have its targets to validate its existence. The targets are: heathens (particularly people of color), Blacks, Jews, atheists, and LGBTQ+.
And ostracizem and violence await those who don't submit.
