No, but the DOH has twice confirmed facts that logically mean Factcheck is a forgery.
I think we can say that it is a fact that the Factcheck COLB is a forgery - unless the DOH has been lying to us, in which case we STILL need an investigation.
I think we need to separate fact from opinion. In all these many posts, nobody has successfully refuted the claim that Okubo’s statement, together with what we observe in the birth certificates themselves, prove that Factcheck is a forgery. I invite you to try to do so, but unless you can, the conclusion is well-supported and should be accepted as fact at least unless and until some information refutes it.
Unless, of course, you're an advocate of a police state, where folks can generate investigations against anyone they wish, simply based on "suspicions."
