Do you claim the people are made-up, SF?
If a Historian wants to prove that person X said a particular quote, do you think they tell their colleagues, "Oh, yeah, check this site. X person said it." Um, no. They use the historical method to affirm historical data, whether its quotes, interviews, or events. So, no, the quotes do not automatically stand for themselves. What stands for itself is GOOD evidence, and telling us to just "find sites with quotes" is not good evidence and not the way it works. And since you're making the claim, you have to prove to us via demonstrable evidence, that all these quotes and eyewitness testimonies are real, i.e., verbatim, an accurate depiction oef events, etc, etc, etc. This is what historians do when attempting to verify any historical event, quote, etc.
So, was Abraham Lincoln "made up?" No. But that does not mean we are not going to need verifiable proof that he said X quote or engaged in X historical event. As such, believing or not believing if these people are made up has absolutely nothing to do with anything. Even people we know existed, still requires evidence that they said X quote or engaged in X historical event. Hell, religious people even provide some evidence that Jesus said X quote or engaged in X historical event. Yet, you cannot even provide some solid evidence from credible sources that these quotes exist. Cross-references would help to support the quote. Now, is there a good chance that these quotes are real from eyewitness testimonies? Yes, there is a very good chance, however, I cannot determine this until you provide the evidence. I await your evidence.
I know, I know, it sucks when you have to provide ACTUAL evidence to support a claim. That damn evidence!!!
But I will no longer go back and forth with you. I have used logic and reason to state my case. You have done nothing of the sort. I will check back to see if you provided any evidence.
