I'm going to completely ignore the line a jokes that involves pointing out how he provided a birth certificate from the very beginning and people kept modifying their demands each time he met them.
The demands for a full long form birth certificate were consistent and never changed. For the vast majority of people who cared at all about this issue, it was always about a belief that the documentation he provided was not sufficient to prove natural born citizenship status.
Instead I'm going to focus on that last part. It seems to me that you accept that he has at some point proven to your satisfaction his natural U.S. citizenship to you, correct?
Of course. Me and everyone who isn't a nutty conspiracy theorist. The problem is that you are conflating the two groups. The fact that there exist a small number of people for whom no evidence will ever suffice does not invalidate the view of a larger group that there is such evidence and it could easily be examined, but for some reason it's being hidden instead. Once that was no longer the case, that group was satisfied and moved on.
Ok, here's the thing. To the majority of birthers, he still hasn't.
Who? And aren't you playing with the term "birther" now? If before Obama provided his long form birth certificate every single person demanding that he do so was labeled a "birther" (as I was on many occasions), then I think it's overwhelmingly true that the vast majority of "birthers" were satisfied by the long form birth certificate. If you're now attempting to change the definition of birther to mean only the conspiracy theorists for whom no evidence will ever suffice, then that's a whole different story. I was never a member of that group, and most of the people demanding to see Obana's full birth certificate were never a member of that group.
In either case, my own position on the issue was never that of a conspiracy theorist, right? So either most "birthers" had a legitimate question which had a real answer *or* most of those who were labeled "birthers" never were. Pick one.
It may no longer be profitable to show them dancing around crazily in the news, but absolutely nothing has changed since the Donald Trump fiasco. If I drive south on the highway near where I live I will still see a sign that says "Where's the birth certificate" paid for by world net daily. He might have strangely convinced you, but everyone who doubted him stills doubts him. There is no threshold of proof that will please them.
Who is this "everyone" you imagine to exist? I have not heard a single person make a claim that Obama isn't a natural born citizen since he presented his long form birth certificate. I'm pretty sure you haven't either. You have to actively go looking for the small number of true nutters to find anyone still trying to make that argument. Hell. When was the last time we had a thread about this? When was the last time it was mentioned in the news?
I think you are grossly misrepresenting (or just plain misunderstand yourself) the true numbers of people for whom the only issue they had was an honest belief that the documentation Obama initially provided was not sufficient. Do you have any evidence that there are even close to as many people today who even care about this anymore? Because the near total lack of *any* mention of this after years of nearly constant talk about it would seem to suggest you are wrong.
