We are the third group of Latinos in the US with about 2 million pep, only behind Mexicans that are more than 35 mil and Puerto Ricans that are more than 4 mil. As a Salvadoran who was raised by an American, I can tell you that the majority of Salvadorans are Pro-America. According to wikipedia "Salvadorans may be the most pro-America people in the world." That is because a lot of our people were helped with something called tps to work here legally.
A little bit off topic but Monica Lewinsky has a Salvadoran-Jewish father, unlike other groups of hispanics, we come in all shapes and social backgrounds, may be the reason why most of us are pro-America, some politics involed as well.
While it's been my personal experience that Salvadorans are pro-US, I'd think they have more reason than most to hate the US govt/politics, I would think, given it trained/backed death squads during the Civil War.
The war in ES was bad but a lot of us came here in massive numbers, worked 3 jobs, opened small businesses, sent our kids to college and here we are. My mom owns 2 houses in ES. Paul Walker was killed driving a car next to a Salvadoran, the owner of the car was Salvadoran. A lot of us are living the American dream and we are still sending money back home. Heck, a lot of Salvadorans may go to Brazil to pull for the US, our NT suck and we love soccer, we refer to the US as "our house, the country that gave us opportunity."
