I was born and raised in Kansas, and my girlfriend and her family immigrated here from Central America about 18 years ago.  We've been together for a few years now.

Recently, we've started the talks of children. Everything was fine, until she told me she wanted our children to learn English and Spanish 'at the same time' and how 'we will speak Spanish at home'(Even though she knows I don't speak Spanish and have no ambition to learn anymore than I already do) 

I put a stop to all that and told her since we live in America, where English is mainly spoken, they will learn English first and when they're older if they want to start learning Spanish they can. I also told her I would not learn Spanish just so I could communicate with my family when I'm in my own home.  she got very upset. She said I was being "disrespectful to her culture" and I was being a "basic Trump supporter" 

I'm thinking logically here. We live in the Bible Belt, where everyone speaks English, it will just be easier for our children to speak the language everyone else is speaking first. Her family all knows English, so I don't see why she's worried about this so much.
