I honestly can't think of much of anything.
Most of the birthers don't even get into the details. They just sling insults. DiogenesLamp is currently the main defender of the birther BS. I have a list of several dozen bogus claims made by him and a few of the other birthers. If the BS continues I will probably eventually get around to writing up all of the BS arguments and exactly WHY they are BS. So there's no direction for them to go except down.
His pattern is to make a bunch of fallacious claims and then keep repeating them. You debunk one, he moves to another. You debunk that, he moves to another. Lather, rinse, repeat. Eventually he comes back to the same ones, because he only has a limited set of BS. Fairly large, but still limited.
There was an incident in which he falsely accused me of deliberately hiding stuff because I didn't include all of a John Bingham quote that had all the wording he liked. The accusation was complete and obvious BS because earlier in the same thread I had actually included a quote from Bingham that said pretty much exactly the same thing.
He also complained about Rawle because he came from a Loyalist family. He also accused Rawle of being a liar. Fine. But like I say, there are other things about Rawle that haven't even been brought to light.
Well, I'll mention a couple. Rawle's grandfather once hired a young guy to do a printing job. The young guy wanted to get into the printing business, and the elder Rawle was his very first customer.
The young man's name was Benjamin Franklin, and that began a decades-long friendship between Franklin and the Rawle family.
In fact, DiogenesLamp has made much of the fact that Rawle went to England to study law. Ah, but do you know why? The US was so torn up with the War that opportunities to study there were limited, to say the least. And Rawle knew before he ever left for England that his plan was to go to England, study, and then return to become a lawyer in Philadelphia.
No matter which way the War went.
After about 7 months (I believe, I'm speaking from memory here) Rawle cut short his studies in England because the war was winding down, and he was eager to get back to Pennsylvania. On his way back, he bopped over to Paris to visit... guess who?
Benjamin Franklin.
Franklin's Society for Political Enquiries was an arm of the core group of Revolutionaries who started our country. They met in Franklin's house, which was THREE BLOCKS from the site of the Constitutional Convention, and they did so in preparation for that Convention. Rawle was there. He even served as the group's consultant on immigration in the runup to the Constitutional Convention, so he obviously knew something about citizenship.
George Washington and Franklin were members of the group, and it seems to be there that Rawle grew close to Washington.
The Society included at least 6 of Pennsylvania's 8 delegates to the Constitutional Convention, so it wasn't just Washington and Franklin that Rawle spent time with. I'd have to look it up again, but I'm pretty sure that all 6 of those signed the Constitution. So Rawle seems to have known at least about 1 out of every 6 or 7 signers of the Constitution.
You are asking Jeff if someone proved him wrong? What answer do you expect him to give you?
