Hi other white folks, can you fucking *stop* splitting hairs over the evidence of racism when it is presented to you? If it's not obvious to you, you should take that as a sign that you have things to learn, not that the accusation is wrong.
Signed, someone who is very tired of it becoming difficult to track down the origins of accusations because of this fucking behaviour discouraging people from providing receipts in the first place. You're not just directly harming the victims this way, you're also making things much harder for everybody actually trying to work on the problem.
