There better be a sensible reason for this statement

From the Abstract of a talk this coming wednesday by critic E. San Juan, Jr. :

"Thus, the promotion of regionalism/regional literatures and cultures, while praiseworthy in preserving indigenous forms, can only drain resources from the project of the national struggle for true sovereignty, without which a national culture/literature of the Filipino masses the workers, peasants and middle strata, including ethnic communities would be impossible"
