What’s the national language of the US? Oh, wait, there is none…. (and no, Trump making an executive order in March doesn’t make it so, those executive orders aren’t laws, they are suggestions) That is why people are calling you out for racism, though I don’t think that is your point personally. I think your point is that unqualified people shouldn’t be driving 80,000 lbs bullets on the roads surrounded by families, and reading signs would be part of qualifying. (edit: which this guy most definitely failed at) Everything else is spot on with what you’re saying, but no one needs to speak English in this country.
