Founded by Thande and Susano, this is (as the name suggests) an association of people who start frothing at the mouth when others get ethnic terminology wrong. See also the P-gah.
Thande - people who think that all Celts are Gaelic;
Susano - confusion of “German” with “Germanic”
Ridwan Asher - confusion of "Malay" with “Malay Race”
Petike - getting stuff about Czechs, Slovaks, Hungarians and various minor nationalities worldwide wrong
