I have no idea what your point is with that comment. If you think the government in place is a result of centuries of systemically corrupt oppression and then you turn around place faith in that same systemically evil government you're either drowning in cognitive dissonance or you're just a hypocritical authoritarian that's ok with the "evil" as long as it puts your agenda in place.

The 3rd alternative is that you're not aware of what BLM means when they discuss systemic racism. It is not just guilt, it opines that the entirety of western civilization is corrupt due to it's creation by racist evil white men.
