“I gather from the gist of your arguement that we should ignore the BC issue in case we might be wrong”
No, I think you are wrong. It’s also not that it should be ignored, but that it’s been given quite enough attention, beyond propriety. Even if birtherism were right, there’s a more appropriate way to go about it than pretending every little bit of evidence that at best raises more questions than it answers is a slam dunk.
And who claimed that this was a slam dunk?
A full glass eventually spills over the rim, doesn't it?
