I agree with you. I served with Puerto Ricans in the military for years, both on active duty as well as with the National Guard and Air National Guard. They fought and died as brothers in arms in all our wars. This twitter attack is BS.
I went to college in PR in the early 70’s. I had gone to high school on the mainland at the height of anti-Americanism during the war. I found far more true-blue America-backers on campus in PR than here.
Yes, there was an Independence faction that was anti-American, but they were small in number compared to the pro American kids. I am not Puerto Rican looking, but I was not discriminated against in the least in PR. Fond memories of PR and its people.
