OK, I think I get it now. When you said there’s no evidence that “they were married or that they even knew each other”, what you meant to say was that there’s all this evidence...
The Hawaii DOH Marriage Registry
Their divorce papers (if you think that’s not prima facie evidence for a marriage, get someone you know who’s single to apply to the courts for a divorce)
Anne Dunham’s registration from August 1961 for the Univ. of Washington in which she applied using her married name.
The internal INS memo from April 1962 which not only mentions the marriage but refers to the likelihood of bigamy.
Obama’s April ‘64 application for extended stay in the US which refers to the marriage.
... but that you’re not buying any of it.
I didn't buy the birth in Queens Hospital, the various Birth Certificates, the loving marriage where the “girl from Kansas” and the man from Kenya “fell in love” and lived together in Hawaii until Obama Jr. was two years old.
I didn't buy Obama registering for Selective Service a year before registration went into effect. I didn't buy the fake Social Security number. I didn't buy Obama first meeting Bill Ayers at a fund raiser at his house in 1995. I didn't buy Obama writing Dreams from my Father. I didn't buy Obama attending Rev. Wright's Church for 20 years and never hearing his sermons or knowing his positions. I don't buy Obama being a genius and a great president.
As a matter of fact I don't buy most of the false Obama biography. I keep an open mind and look at things in context and see if they add up.
