Maria Poblet, a community organizer for San Francisco’s “sanctuary city” policy, recently retweeted a “Make America Mexico Again” hat on two separate days on her Twitter feed.

Maria Poblet is the executive director of the Causa Justa :: Just Cause group that is working to expand San Francisco’s “sanctuary city” law. A woman with Causa Justa :: Just Cause tried to block this reporter from filming the group’s members violating the rules at a Board of Supervisors meeting Tuesday night, then caused me to be removed from the public meeting.

The “Make America Mexico Again” meme is a takeoff on Donald Trump’s strong pro-American and anti-illegal immigration stance.

However, the underlying message of the meme is serious. Many Mexicans and Mexican-Americans think that states including California, Arizona and New Mexico were stolen from Mexico and belong to them.

A 2012 poll found that 58 percent of Mexicans think that the Southwest portion of the United States rightfully belongs to Mexico. As UPI reported:

The group, over the period May 25-26, asked a series of questions of 801 Mexicans. A total of 1,015 U.S. citizens were questioned between May 28-30. The data have a margin of error of 3.5 percent.

Asked if they believed the U.S. Southwest rightfully belonged to Mexico, 58 percent of respondents in Mexico said it did, while 28 percent disagreed. A similar number — 57 percent — stated agreement with the position that Mexicans have the right to enter the United States without U.S. permission. A total of 35 percent disagreed.

The public lie told by groups like Causa Justa :: Just Cause is that they are simply supporting “immigrant rights.” The reality is that they have a real agenda that they generally keep from the general public, because they know that their real views are repugnant to the public at large.
