I don't care how many languages he speaks - or doesn't. Speaking in spanish is an insult to all the Germans, Irish, Polish, Chinese, etc who came here and would like to hear the speech in their language. What makes spanish so special?
Not a thing, except that Spanish and French are pretty much the only second languages spoken among a large group of native born Americans several generations away from their ancestral country anymore, but French and Spanish were more widely used than English until a few centuries ago.
My husband’s family was three generations removed from Quebec, and spoke Canadian French as a second language, along with a lot of other people in states that share a border with Canada. Damn near everyone of any French ancestry in Lousiana speaks Acadian (cajun) French just like we speak Spanish in the Mexican border states, even though they are hundreds of miles and about 300 years from Canada.
Of course English is the language of America, but many of us learned either at home or at school to speak a second one. In the far past, it was considered a mark of good breeding and education, and furthered one’s career and social ambitions. Call it a snob value that has persisted, but I think any world leader should at least be somewhat conversant in a second language-although I understand that Mandarin Chinese is a bad choice because of the many nuances.
If a bunch of people want a speech read in Chinese, German or Polish, I don’t see why it shouldn’t be, There might be some problems with the Irish, though-not many people speak Gaelic.
