And they absolutely DID realize it back then.
Do you know what you're talking about? I have no idea since you are running in circles.
I gave up debating Birthers months ago. Now I just bait them into taking preposterous positions in defense of Birtherism. And here we have you stating that Arthur was not eligible to be President, and people knew it at the time, but they just let him go on and be President anyway because they didn't want to hurt his feelings, or because the giant conspiracy to put Brits into the Presidency of the United States is actually 150 years old, or whatever.
I agree that you have to take that position to be a consistent Birther, but wow. Do you have any idea how preposterous that sounds the non-Birthers? It makes me feel kinda bad for baiting Birthers. Its like shooting ducks over baited ground. At the city park. With a belt fed, full auto, 12 gauge mounted on a pintle. It makes me wonder if you are secretly not Birther, but just trying to make them look ridiculous. Parsy is that you?
