I have read the explanation of how you come to have anti-B antibodies even if 
you have never been exposed to antigen B.  What I am asking is what keeps your 
body from making antibodies against your own blood type, assuming everyone has 
the same bacteria in the GI system, should they not all make the same 
antibodies?
