In 1994 I signed up for Japanese in high school, but there wasn't enough interest so the class was canceled and I ended up taking Spanish instead. Spanish has sometimes been useful to know but I've still never (not for a lack of interest just never happened) been to Spain or anywhere in Latin America outside of Miami and San Diego. The last time I had an opportunity to use Spanish was when I was in Moscow and took my car to a garage ran by Uzbeks. None of them spoke English but one of them knew Spanish. :D
Furthermore, these European languages are closely related to English both in terms of grammar and vocab, and are written in the Latin script, and that makes it easier for students to get results in them. That may well be one of the reasons that teachers are more readily available in these languages, as well as higher education, i.e. the training of teachers, is easier.
Other than that, I agree.
It's literally in the name "American Sign Language"
