Yes, we’ve seen the stamp. But that doesn’t mean it’s not worth while focusing on what prove to be numerous problems and discrepancies.
For instance, the White House says that they have posted a copy of a paper birth certificate on their website—actually a COLB, as you recognize.
Only problem with that, is that some of the many discrepancies would not be there if this were merely a copy of a paper COLB—even a forged paper COLB. There are also numerous signs of computer manipulation. This is not merely a copy, not even of a fake COLB. It’s fake on top of fake on top of fake.
I doubt if the State of HI stamp actually has an “X” instead of an “H” in one of the words.
