"How are we to know where your quote ends?"
It ended with that famigerated last declarative sentence. No other text followed it. I understand it can at times cause confusion. It did confuse you and it was resolved.
"In any case, why are we not allowed to respond to points you make by quoting text from another source?"
But you ARE responding to quotes not attributed to the poster, and I'm trying to respond to them as best I can.
"If you quote something you should be prepared to defend it, not disclaim all knowledge of what you quoted as you did to me."
Absolutely agree that one should be prepared to defend it. But, I did not disclaim all knowledge; I only disclaimed that last sentence being attributed to me, which was not.
That is just ludicrously disingenuous.
