You can take up that cause if you like.
I don't need to; I'm personally satisfied with the evidence I have.
But are you satisfied with the evidence that Joe Biden is Constitutionally eligible for the office he holds? If so, why? He's produced less evidence than Obama, but nobody's demanding that he produce any birth certificates, or parents' marriage certificates, or passport records, or kindergarten records, or baptism records. Do you even know what hospital Biden was born in? Why are you holding Obama to a different standard than Biden?
And if you're not satisfied with Biden's credentials, why aren't you demanding to see his records too? It's just as big a transparency issue. If you're going to claim that Obama should release something, it's not really much more trouble to append "and so should Biden." Failing to do so makes it look like Biden is held to a different standard, just like above.
