Even the L.A. Times has admonished demonstrators to lose the Mexican flags, since it has created a positive backlash for Trump.
Too bad people always have to tell them that, they need to carry the flags until everyone understands what they mean. Those carrying the Mexican flags are literally claiming our land for Mexico. It is part of Reconquista to them.
This movement began many years ago and people said it wasn’t real, or true. Made up by racists on the border. It has been and is a real thing.
This was an issue years ago during the May Day parade (in LA, I believe); leftists told the braceros that the flags were hurting their image in the eyes of Americans (who vote), and the flags disappeared in subsequent years.
While Trump can’t say so politically, his proxies need to make it clear that American taxpayers are providing everything for these parasites for free; those flags should provide a nice boost for Trump. Mexicans may own southern CA, but there are 49 other states in this country.
