“but we are, all of us, responsible”
If you want to argue that they should be treated well, okay, but don’t try to blame me for what people I don’t know did in a different state 30 years ago.
Gen. 4:9And the LORD said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother’s keeper?
... and all that rot.
Since I am a Texan, though I've never lived in Dallas, I am more directly responsible than you. But we all bear some responsibility. Not blame --- but the responsibility to do your part to make sure that such things don't happen in your baliwick.
