I think I sort of agree with you?
It felt like you were falling into the common trap of seeming angrier about "people complaining about X" than "X" even as you mentioned that X was bad.
The mentions of great crimes all seemed a bit remote and dry, whereas the accusations of people being overdefensive and deflecting using it as an excuse seemed a bit more heartfelt.
I think from the inside it can be hard to judge that balance and put yourself in the position of someone who might weight things differently. A problem of "privilege" which you bring up, but don't seem to be swayed by, though I've never met anyone who thinks it doesn't apply to other people.
