::So no one on this list should have the title "Sir" before their name?  I still feel unclear about making such a change to several names in this article (even after reading MOS:HONORIFIC).  I propose deleting all instances of "Sir" and making some note in the beginning about how many heads of government also have that title.  Or is the reason for those people having "Sir" because they were more often referred to as such by reliable sources (as per MOS:HONORIFIC)?
