If you believe the certificate is fake, do you think that the Governor of Hawaii and Director of Health and State Registrar are all in on it?
Just this week the DOH again verified the information on the birth certificate (pdf).

Also you said that the COLB is an abstract and the LFBC is not. This is not correct. The original BC that is in the bound volume at the DOH contains additional information (medical data) that was collected at the time of birth. The medical information was required by the National Institute for Health Statistics although the individual states could also have addtion medical data. That medical information is not included on the LFBC given to the parents. So in fact, the LFBC is also an abstract.
Look on President Obama’s LFBC or the Nordyke’s LFBC, you will not see a box listing weight of baby, yet this is a required (by NIHS) piece of information.
Ah, yes, a poorly crafted "are you still beating your wife?" question. Flaunting your stupidity in public won't get you anywhere.
