[DiogenesLamp]

And yet, DiogenesLamp himself is happy to cite the British press or British authors whenever they can be used to serve his purposes.

Well first of all, this is a "You're another" fallacy. (Tu quoque fallacy.)

And secondly, I don't think you can find any examples of me citing the modern British press on anything. The 1862 example of which you are thinking is self evidently true on the face of it.

"The principle is not that a human being cannot justly own another, but that he cannot own him unless he is loyal to the United States."

DiogenesLamp: "Well first of all, this is a "You're another" fallacy. (Tu quoque fallacy.)"

But that's not a "fallacy", it's a legitimate argument -- in court it's called "standing".
If you are accusing me of something you yourself are guilty, then you have no "standing" in the court of public opinion.

And here's how you know I'm right: you yourself use "tu quoque" logic whenever that suits your own purposes.
Consider just one example of a Lost Cause tu quoque argument: "Northerners were slavers too!"
