This is not a slight against PR or it's poeple. I would prefer we all speak english, as it unites us rather than makes divisions out of the United States of America and it's protectorates.
We speak English. In fact, Puerto Rico is one of the few US jurisdictions that actually has English as an official language (along with Spanish). Heck, I'm writing to you in English. You could live here for years and years and not need to speak Spanish at all. I know quite a few people that do.
