Concerning the Article:  "Hinayana Buddhism From Wikipedia" as a note:  In Thailand, where the National Religion is Theravada Buddhism, the National Museum, in its display concerning the history of the Kingdom of Thailand (specifically the Sukkhothai and Ayutthaya periods), makes a very clear distinction between Theravada and Hinayana Buddhism listing it as a seperate  religion (along with Mahayana Buddhism and Christianity)that was at times under the patronage of the King.  It would appear that the Thai Hierarchy of Buddhism has no confusion concerning the use of this term.
