I cannot conceive of a "stronger" explanation for what the GP stated. What kind of good faith argument could possibly be assumed in that guy asking that maybe reexamining Redline laws isn't the worst thing. It's a vile thing to say, and a statement made, I can only assume, in utter and wanton disregard of racial history of the United States.

It's a bit shameful that you flagged the parent and not the grandparent, who seems to be playing devil's advocate purely for the sake of an argument.

It's very clear what they were saying, is that if one follows the law at all time there is no chance that a bad thing will "accidentally" happen.

You are actually the one violating that policy.
