If the prevailing attitude of many Vulcans against Amanda Grayson - and presumably other humans - was one of prejudice, why would the VHC allow her access to the Vulcan 'Holy-of-Holies', The Katric Ark? 
I thought that this was a bit of an incongruity; presumably Sarek's colleagues got to know her and respect her abilities and attributes, or maybe it's a plot inconsistancy.
What do you think?
