The problem is there are some kooks in the birther movement. The 9-11 truthers are all kooks. Equating them is not correct.
And what is a kook? I know of none in the birther movement. They just want the BC (long form) and cannot understand why they can’t get it since it is a requirement for the job. There are perfectly legit answers why Ozero cannot furnish that? I don’t know of any.
