Irishman of Asia is a some sort of racist insult given by the Englishmen, English and Americans saw Irish people as unruly,rowdy and uneducated which is NOT true they were plagued with poverty 100 years ago like us at the time but it wasn't all the Irishes' fault of course they were being oppressed by the English and early irish immigrants who lived in america were not treated well most Americans treated them as third class citizen like they treated the African Americans. The Americans and English at that time treated the Filipinos,Irish and Other "inferior" races like that.
I have 3 dream scenes to become canon in Hetalia, Fili having a Noche Buena scene with all the Latino family, An all Asean club for Hetalia gakuen and a drinking sessions with Ireland,Germany,Prussia,America,England.
The Irishman of Asia? First time I hear of this nickname, a rather interesting one though! Poor Philippines, I don't think she entirely expected to be invited out to a drink so suddenly. England certainly looks very irked. Great picture!
