I get the Canada claim, as I think his mother was supposed to have been just below the Canadian border around the time of his birth, and expected to maybe have crossed over into Canada for a free hospital delivery.
But what would be your source on SAD not being his mother and FMD not his father? I don’t know that theory at all.
Somehow you managed to avoid reading the very, very long and detailed research threads from around 2008-2012 and some still are being added to.
You can do searches and find the threads.
Simply put, there is not one shred of evidence to support the claims that those two individuals are his parents. None. Only a forged birth certificate and his say-so, and a ghost written “autobiography” (written by Bill Ayers) which even starts with the caveat that it isn’t all factual.
