That's a curious argument.
You do know that "white" is not a scientific term?
In Africa, North Africans are often called "white".
In European cultures, often Southern European groups were not considered to be "white".
In the Islamic conquests during the years 700 and on, Muslims systematically destroyed
Christian culture and structures in Asia and North Africa. None of the groups involved,
would fit the modern American description of what "white" is.
In Christianity, an individual will be judged on what they themselves chose to do
in their life. Guilt, in the Christian worldview, is heavily individual.
When reasoning about guilt and people groups, you need to very precisely
define the people groups. Then you need to very carefully define what you think
is the individual guilt, of those who fit into this people group.
In American law, if you wish to demonstrate that an individual is guilty of some
evil that a group has done, then you need to demonstrate
1 Their membership in that group
2 That the group, as a whole, is guilty of something.
If I have an ancestor who was a murderer, do I share in that guilt?
If I had an ancestor who was a thief, am I guilty of that sin?
If you impute to me guilt over "micro aggressions" for example, that I
cannot even detect, how is this different than arbitrarily imputing guilt
to me?
In the Christian worldview, every human being is morally-ethically responsible
to keep God's ME law. This is not a basic assumption of the American social
justice groups. Nor do the American social justice groups make distinctions between
Christians who struggle to keep God's ME laws, and secular people who do not.
This leads to all sorts of "racial" or "sexual" group guilt imputing, that bypasses
God's ME law.
Many Christians understand the injustice in this crude group generalization.
Many American social justice groups, do not.
