"In San Jose on Thursday, a volatile crowd outside a Donald Trump rally assaulted numerous attendees. They punched a man in the face, knocking him to the ground; bloodied another man by bludgeoning the side of his head with a duffel bag; trapped a woman against a glass door, pelting her with an egg and other objects; snatched a cap off a man’s head, lighting it afire on the street soon afterward; and perpetrated other hateful acts against total strangers, with many fellow protesters cheering them on and a brave few fervently pleading for nonviolence.
The bad actors in San Jose should be arrested, prosecuted, jailed, and broadly condemned. In addition to attacking fellow human beings, they did violence to the shared right to assemble. They assaulted the American inheritance of a politics that is decided peaceably at the ballot box by the people, not in the streets through force or intimidation." The Atlantic
If the people waving the Mexican national flag at US political events are US citizens, they are disloyal to the United States and collectively harbor irredentist ambitions for the US Southwest on behalf of the Mexican state.
These people are attempting to block American citizens from exercising basic political rights through intimidation and violence when they think it necessary.
They must be aware that they are fuelling Trump's campaign as living symbols of the illegal alien presence that he and his supporters object to. If he is elected they will have themselves to blame but I doubt that they will do that. pl
