The problem with 'birthers' is they constantly ignore facts and come up with little snippets of things that are NOT FACTS and call them facts. As they say, you are entitled to your own opinions, not your own facts.
In the above links, hearsay is presented as fact.
Besides the REAL birth cert, the living witneses, there were printed birth announcements in TWO local papers. From wiki:
"In 1961, birth notices for Barack Obama were published in both the Honolulu Advertiser and the Honolulu Star-Bulletin on August 13 and August 14, 1961, respectively, listing the home address of Obama's parents as 6085 Kalanianaole Highway in Honolulu. On November 9, 2008, in response to the persistent rumors, the Advertiser posted on its web site a screenshot of the announcement taken from its microfilmed archives. Such notices were sent to newspapers routinely by the Hawaii Department of Health.
In an editorial published on July 29, 2009, the Star-Bulletin pointed out that both newspapers' vital-statistics columns are available on microfilm in the main state library. "Were the state Department of Health and Obama's parents really in cahoots to give false information to the newspapers, perhaps intending to clear the way for the baby to someday be elected president of the United States?" the newspaper asked."
