Your perception is mistaken according to the letter of the law, spetznaz. Even the online resource that is most dubious of "birther" claims, FactCheck.org, clearly validates what FReeper ExtremelyExtremeExtremist has claimed:
When Barack Obama Jr. was born on Aug. 4,1961, in Honolulu, Kenya was a British colony, still part of the United Kingdom's dwindling empire. As a Kenyan native, Barack Obama Sr. was a British subject whose citizenship status was governed by The British Nationality Act of 1948. That same act governed the status of Obama Sr.'s children:
British Nationality Act of 1948 (Part II, Section 5): Subject to the provisions of this section, a person born after the commencement of this Act shall be a citizen of the United Kingdom and Colonies by descent if his father is a citizen of the United Kingdom and Colonies at the time of the birth.
In other words, at the time of his birth, Barack Obama Jr. was both a U.S. citizen (by virtue of being born in Hawaii) and a citizen of the United Kingdom and Colonies (or the UKC) by virtue of being born to a father who was a citizen of the UKC.
Obama's British citizenship was short-lived. On Dec. 12, 1963, Kenya formally gained its independence from the United Kingdom. Chapter VI, Section 87 of the Kenyan Constitution specifies that:
1. Every person who, having been born in Kenya, is on 11th December, 1963 a citizen of the United Kingdom and Colonies or a British protected person shall become a citizen of Kenya on 12th December, 1963...
2. Every person who, having been born outside Kenya, is on 11th December, 1963 a citizen of the United Kingdom and Colonies or a British protected person shall, if his father becomes, or would but for his death have become, a citizen of Kenya by virtue of subsection (1), become a citizen of Kenya on 12th December, 1963.
As a citizen of the UKC who was born in Kenya, Obama's father automatically received Kenyan citizenship via subsection (1). So given that Obama qualified for citizen of the UKC status at birth and given that Obama's father became a Kenyan citizen via subsection (1), it follows that Obama did in fact have Kenyan citizenship after 1963.

However, that is me speculating. I will do some background research on what that law entailed, and get back to both of you. I have my suspicions that it did not pertain to the Indian dukawalahs and railway laborers, or the African clerks and farmhands, but rather to the settlers who, if you know British law then, knew that citizenship would 'expire' after one generation cycle.
However, you posted information, while all I am doing is speculation. To remedy that I will rout about and see what I dig up. After all, this is FR and not DU.
As for the rest of the COLB matter, I think that whether or not it is a rope-a-dope, it is still an important issue that deserves merit. After all, it is important that the head of a country, be he/her real or ceremonial, be OF AND FROM that country. Commonsense stipulates that. Have a blessed day.
