I wouldn’t care even if it the spanish speaker thought I was rude. I was in high school in the mid to late 90’s, and I never took a language class(Spanish & German were both offered), and the reason I never took a language class is because this is the USA, and we speak English here. I’m not about to learn another language to suit some illegal alien who snuck over the border.
You’re entitled to your position, and I agree that we should not be forced to learn another language to suit illegals.
However, picking up a second language is a good thing. Before colleges became watered down, Latin was a requirement to graduate.
